`
`of H-1B visas who work and reside in the Austin area.12 Additionally, Micron Technology has
`
`been the employer of approximately seventeen recipients of H-1B visas who work and reside in
`
`the Allen, Texas area.13
`
`21. Micron, directly and through agents, regularly conducts, solicits, and transacts
`
`business in this District and elsewhere in Texas, including through its micron.com website. For
`
`example, Defendants employ sales and marketing employees that regularly offer to sell, sell, or
`
`otherwise distribute flash memory products in this District and elsewhere in Texas.
`
`22.
`
`In particular, Micron has committed and continues to commit acts of infringement
`
`in violation of 35 U.S.C. § 271, and has made, used, marketed, distributed, offered for sale, and
`
`sold infringing products in Texas, including in this District, and engaged in infringing conduct
`
`within and directed at or from this District. The infringing flash memory products have been and
`
`continue to be distributed to and used in this District. Micron’s acts cause injury to Vervain,
`
`including injury suffered within this District.
`
`23.
`
`Venue is proper in this District under 28 U.S.C. §§ 1391 and 1400(b) because a
`
`substantial part of the events or omissions giving rise to the claims occurred in this District, and
`
`because Defendants have committed acts of infringement in this District and have a regular and
`
`established place of business in this District.

`
`25. Micron Semiconductor and Micron Texas are wholly owned subsidiaries of
`
`Micron Technology. Micron Technology does not separately report revenue from Micron
`
`Semiconductor or Micron Texas in its filings to the Securities Exchange Commission, but rather
`
`reports combined revenue from its various products and subsidiaries.

`
`G.R. Mohan Rao is the sole inventor of the Asserted Patents.
`
`Dr. Rao is the inventor of approximately 111 U.S. patents and the author of at
`
`least 15 technical publications spanning several decades.
`
`33.
`
`Dr. Rao has been an innovator in the semiconductor industry since the 1960s.
`
`After receiving his Ph.D. in physics with a specialization in electronics in September 1968 from
`
`Andhra University in Waltair, India, near the village where he grew up, Dr. Rao traveled to the
`
`United States to attend a graduate program in physics at the University of Cincinnati, fulfilling
`
`his lifelong dream to study in the United States.
`
`34.
`
`Shortly after beginning his studies at the University of Cincinnati, Dr. Rao found
`
`a bulletin indicating that Prof. William Carr of Southern Methodist University (SMU) was
`
`looking for a graduate assistant for his work on MOS transistors. Dr. Rao called Prof. Carr about

`
`
`
`the opportunity, and by December 1968, after completing the fall semester at the University of
`
`Cincinnati, Dr. Rao had received the assistantship with Prof. Carr, moved to Dallas, Texas, and
`
`enrolled in a Ph.D. program at SMU in electrical engineering.
`
`35.
`
`At the laboratory at SMU, Dr. Rao was able to build MOS devices from scratch.
`
`In the 1969-1970 timespan, while attending SMU, Dr. Rao also worked in the SMU laboratory
`
`with Jack Kilby of Texas Instruments, a pioneering electrical engineer who would later receive a
`
`Nobel Prize for his work. In early 1972, Mr. Kilby set up an interview for Dr. Rao at Texas
`
`Instruments’ Houston facility, then the home of Texas Instruments’ MOS-related work.
`
`36.
`
`Dr. Rao began working for Texas Instruments in June 1972. He would go on to
`
`work for the company for 22 years, until 1994. Dr. Rao rose through the ranks at Texas
`
`Instruments, starting in an Engineer position and ascending to the position of Senior Fellow—
`
`one of 12 out of approximately 20,000 engineers at the company at the time. He then moved into
`
`a management position, starting as a Vice President in 1983 and becoming a Senior Vice
`
`President in 1985.
`
`37.
`
`Dr. Rao received his first patent while working in a process and product
`
`engineering capacity to solve a production problem with Texas Instruments’ 4-kilobit RAM
`
`product. From the late 1970s through the mid-1980s, he worked on and/or managed Texas
`
`Instruments’: (1) 64Kb RAM, in a project management capacity as a Senior Member of
`
`Technical Staff; (2) 256Kb RAM, in a project management capacity as a Fellow; (3) 1Mb RAM,
`
`in a management capacity as a Senior Fellow, overseeing several projects; and (4) 4Mb RAM, in
`
`a management capacity as a Senior Fellow, overseeing several projects. At Texas Instruments,
`
`Dr. Rao also worked on projects involving EEPROM, SRAM, and microcontrollers. In total, Dr.
`
`Rao received approximately 35 U.S. patents during his time at Texas Instruments.

`
`
`
`38.
`
`Some of Dr. Rao’s work for Texas Instruments is featured in the Smithsonian
`
`Institution, in the Texas Instruments Collection.14 For example, the Smithsonian Institution has a
`
`display of Texas Instruments’ experimental 1-megabit CMOS DRAM with one-micron feature
`
`size, produced in April 1985 under Dr. Rao’s leadership.
`
`39.
`
`After his time at Texas Instruments, Dr. Rao joined Cirrus Logic in 1994.
`
`Although Cirrus Logic was a California company, Dr. Rao coordinated a team in the Dallas area.
`
`His work focused on a major project involving integration of a graphics controller and memory.
`
`During his time at Cirrus Logic, Dr. Rao received approximately 22 U.S. patents relating to his
`
`work on integrated graphics controllers and memory. Dr. Rao left Cirrus Logic in the summer of
`
`1996.
`
`40.
`
`Later in 1996, Dr. Rao started a company called Silicon Aquarius. Through a
`
`relationship between Silicon Aquarius and Matsushita, Dr. Rao led a design team in working on
`
`a 256Mb DRAM chip.
`
`41.
`
`After Silicon Aquarius ceased operations, Dr. Rao did consulting work for a
`
`number of different companies and devoted much of his free time to thinking about various
`
`challenges and problems with which the semiconductor industry had struggled for years. For
`
`example, Dr. Rao worked to improve non-volatile memories that are used for long term storage
`
`of data after the power is turned off, and how to reduce the power consumption of those devices.
`
`42.
`
`In non-volatile memories, there are two types of storage cells: single-level cells
`
`(SLCs) that store one bit of information, and multi-level cells (MLCs) that store multiple bits of
`
`information. SLCs are faster, more reliable, and have a longer life. MLCs are less expensive

`
`
`
`and can store more data in less space with less power consumption. While working to improve
`
`these non-volatile memories, Dr. Rao developed inventions that combine the long life and high-
`
`performance of SLCs with the more cost-effective MLCs. The result is the best of both types of
`
`cells – longer life and better performance at less cost. By using the MLCs as the default storage,
`
`the cheaper, more reliable MLCs are used for the bulk of the data storage. Meanwhile, the SLCs
`
`are used for the data that needs it the most.
`
`43.
`
`The claims of the Asserted Patents are directed to patent-eligible, non-abstract
`
`ideas. They address, among other things, specific improvements for controlling non-volatile
`
`memory modules. The claims are particularly useful for flash memory products or other
`
`memory devices that use a combination of SLCs and multi-level cells MLCs. If, for example, a
`
`range of addresses in a MLC memory module fails a data integrity test, the range of addresses
`
`may be mapped to a new range of addresses in a SLC memory module. Also, if a block in the
`
`MLC module is used frequently, the block may be transferred to the SLC module. By doing so,
`
`the reliability and life of the flash memory is increased.
`
`44.
`
`Vervain’s Asserted Patents claim, among other things, a specific implementation
`
`of a solution to a problem in the design and fabrication of flash memories. For example, the
`
`patents identify numerous specific advantages that Vervain’s claimed techniques provide
`

`COUNT I: INFRINGEMENT OF U.S. PATENT NO. 8,891,298
`
`56.
`
`Vervain incorporates by reference and re-alleges all of the foregoing paragraphs
`
`of this Complaint as if fully set forth herein.
`
`57.
`
`Defendants have directly infringed and continue to infringe, either literally or
`
`under the doctrine of equivalents, at least claim 1 of the ’298 patent by making, using, offer for
`
`sale, selling, and importing, without authority or license, the Accused Products in violation of 35

`
`U.S.C. § 271(a). The Accused Products are non-limiting examples that were identified based on
`
`currently available information, and Vervain reserves the right to identify additional infringing
`
`activities, products, and services, including, for example, on the basis of information obtained
`
`during discovery.
`
`58.
`
`The Accused Products meet all the limitations of at least claim 1 of the ’298
`
`patent. Specifically, claim 1 of the ’298 patent recites:
`
`A system for storing data comprising:
`
`at least one MLC non-volatile memory module comprising a plurality of
`individually erasable blocks;
`
`at least one SLC non-volatile memory module comprising a plurality of
`individually erasable blocks; and
`
` a
`
` controller coupled to the at least one MLC non-volatile memory module and the
`at least one SLC non-volatile memory module wherein the controller is adapted
`to:
`
`a) maintain an address map of at least one of the MLC and SLC non-volatile
`memory modules, the address map comprising a list of logical address ranges
`accessible by a computer system, the list of logical address ranges having a
`minimum quanta of addresses, wherein each entry in the list of logical address
`ranges maps to a similar range of physical addresses within either the at least
`one SLC non-volatile memory module or within the at least one MLC non-
`volatile memory module;
`
`b) determine if a range of addresses listed by an entry and mapped to a similar
`range of physical addresses within the at least one MLC non-volatile memory
`module, fails a data integrity test, and, in the event of such a failure, the
`controller remaps the entry to the next available equivalent range of physical
`addresses within the at least one SLC non-volatile memory module;
`
`c) determine which of the blocks of the plurality of the blocks in the MLC and
`SLC non-volatile memory modules are accessed most frequently by
`maintaining a count of the number of times each one of the blocks is accessed;
`and
`
`d) allocate those blocks that receive the most frequent writes by transferring the
`respective contents of those blocks to the at least one SLC non-volatile
`memory module.
