`
`EXAMTNATION BY COUNSEL FOR RESPONDENTS

`
`O Good morning, Dr
`
`Mr. McAlexander
`
`Good morning
`
`Your expert reports relatíve
`
`to the ''734
`
`A O
`
`were marked yesterday as Exhibit 1 and Exhibit. 3
`
`Riqht ?
`
`(McAlexander Exhibit 1 and Exhibit 3,
`
`previously marked, retained by counsel. )
`
`A Yes, that is correct
`
`O And t.he patent was marked as Exhibit 6?
`
`(McAlexander ExhibiL 6, previously marked,
`
`retained by counsel. )
`
`A That is correct
`
`O Okay. Thank you.
`
`In your anaÌysis you
`
`rel-ied on the legal standards in your expert reports.
`
`Correct ?

`
`O And I take it you received those from
`
`counsel- ?
`
`A Yes
`

`
`' 09:09:15
`09:092I'7
`
`O Okay. LeL's start. with a little
`background terminology. DDR stands for dual data
`
`bit of
`
`rate. Correct?
`
`A Double data rate.
`
`O Double data rate. And that refers to the
`fact that the data is clocked in on the rising edge
`
`and the falling edge of a data strobe. Right?
`
`A That's correct. Basicall-y it's
`
`two data
`
`per cycle.
`
`O And so t.he "doubfe" refers to the fact that
`you can clock a data twj-ce as fasL as the clock rate?
`
`A That would be correct' Yes.
`
`O Okay. Because the data strobe basically
`has the same frequency as the clock rate, has the same
`
`frequency as the clock, rather?
`
`A
`
`ït can, yes
`
`MR. NGUYEN : Ob j ecl:
`
`O
`
`It typi-cally does. Right?

`
`A
`
`Yes
`
`O All right. Now, JEDEC standards define
`
`different
`
`types of DDR SDRAM. Right?
`
`A And by the way, t.he only reason I said
`
`ir
`
`and I said it can, is because the data strobe is
`
`not a clock. So it can, but it doesn't have to
`
`O Right. But typi-cally in the JEDEC
`
`standards it does. Right?
`
`A
`
`Itrs only dependent on whether or not
`
`you're propagat.ing dat.a
`
`O Uh-huh. Right. So sometimes the data
`
`sLrobe will simply be flat because nothing is
`
`happening?
`
`A Right.
`
`lt's not a clock.
`
`O So when you
`
`you have a c1ock, it goes
`
`all the time. And the data strobe sometimes wil-l be
`
`fl-at. And then when yourre reading or writing,
`
`the
`
`data strobe will
`
`A For that period of time, yes
`
`O Yeah. No, Irve seen those timing charts
`
`Now, JEDEC standards define different Lypes
`
`of DDR SDRAM. Correct?

`

`

`
`Right ?
`
`A There are more than that, but at least it
`
`includes those.
`
`O Okay. Now, a data strobe is used to time
`the capture of data that's being sent to or from a DDR
`
`SDRAM. Right?
`
`A
`
`It's used to identify when the data is
`
`avail-able and val-id so that it can be captured

`

`t.hat's in receì-pt is going to choose when it accepts
`
`it based upon receiving the DQS signal that says data
`

`
`that actual capt.ure takes place. And it will be

`

`

`
`Is this a
`
`t.ruth statement or not: A data strobe signal is used
`
`to time the capture of data that.'s being sent to or
`

`

`
`identify
`
`the time in which capture can take place
`

`A
`
`Irm just saying it

`your quest.ion was
`
`a very open-ended question. Alf I did was to qualify
`
`it. Within the matter that r¡re're discussing here, the
`
`ans\^/er IS yes.
`
`O So reference voltages are obviously used
`
`for other things?
`
`A Yes.
`
`O Okay. Al1 right. And that comparison is
`
`made in order to determine whether the data strobe
`
`signal- is larger or smaller than the reference voltage
`
`at any given time. Right?
`
`Itrs higher or l-ower
`
`Okay. Let me just ask that aqain. Yourre
`
`A O
`
`right,
`
`thatrs a bit more precise
`
`Okay. So t.hat comparison is made in order
`
`to determine whether the data strobe signal is higher
`
`or lower than t.he reference voJ-t.age. Rig"ht?
`
`That's correct. At thaL point in time.
`
`Okay. And in differential mode, the
`
`A O
`
`voltage of the data strobe signal is compared to the
`
`voltage of the data strobe bar signal in order to
`
`determine which one is higher. Correct?

`
`hypothet.ical .
`
`ANo
`
`O Okay. WhaL is compared in differential
`mode with respect to the data strobe signal?
`
`A You're comparing the two
`the two are opposit.e in polarity, whenever one is
`high, the ot-her is going to automatically be low- AII
`
`it t s because
`
`you're doing is using
`
`rather than comparing the
`
`the high portion of t.he signal to some mid
`hiqh
`reference points, You're comparing it between the two
`voltage
`signals. So you get- a larger differential
`
`ouL.
`
`So it works bett.er in l-ower voltage
`
`applications. Yourre not. trying to determine which
`one is higher; you're using the two facts that one is
`
`high and one is 1ow, and youtve got a larger voltage
`
`then bet.ween the two than if you did it. to some
`
`midpoint voltage.
`

`
`let me say that again.
`
`lVhen the data strobe signal is lower than
`
`the data strobe bar signal- at the crossing point, the
`

`
`MR. NGUYEN: Same objection.
`
`A That i-s correct.
`
`a Okay. So at the crossing point, I'm qoing
`
`to ask again.
`
`In differential mode, at the crossing
`
`point,
`
`the voltage of the data st.robe signal is
`
`compared to the voltage of the data strobe bar signal

`
`A
`
`lrlell, it's after the crossing point.
`
`3 /Z

`
`Okay. So in differential mode, the voltage

`
`of t.he data strobe bar signal. Correct?
`
`A Correct..
`

`
`I just said LPDDR was the first. generation
`
`So
`
`374
`
`please continue with your explanation
`
`MR. NGUYEN: Objection. Vague
`
`A
`
`I believe, as I recall-, the name given to
`
`the first generation was LP.
`
`O Just LP?
`
`Low-power double data raLe.
`
`Okay. Now. the terms "LPDDRil and I'MDDR"
`
`A O
`
`are used interchangeably. Correct?
`
`A That is correct.
`
`O Okay. And there were subsequent
`
`generations of mobile DDR. Right?
`
`A Yes.
`
`O Okay. For example, there was MDDR 2
`
`Correct ?
`
`A Yes
`
`a And MDDR 2 was also call-ed LP DDR2. Right.?
`
`09 221 : 16
`

`
`VJ.LL.LL
`
`^o.
`09z2Iz2I
`
`That is correct..
`
`And I believe at LhaL poi-nt the MDDR
`
`A O
`
`nomenclature hIAS
`
`was abandoned and the 1ow-power
`
`DDR was just called LP DDR2, 3, 4, whatever?
`
`A Vrlhatever it was. I agree with that.

`one memory conLrolfer to interface with multiple types
