=A0 Hi Sir, =A0=A0=A0=A0=A0=A0=A0 Actually we are doing a project "Power management in = RAM". For that, we want to know whether Partial Array Self Refresh (PASR) i= s implemented in software or not. We have read=A0datasheets & we=A0think th= at PASR is implemented at hardware level. The bank(s) which are not in use = will be switched off (before that the data in that bank(s) will be moved to= active bank). We are not getting such facility in mobile DDR RAM.=20 =A0 Thanks, --- On Fri, 9/26/08, Chuck Swiger <cswiger@mac.com> wrote: From: Chuck Swiger <cswiger@mac.com> Subject: Re: facility for mobile DDR RAM To: johnseth_2007@yahoo.com Cc: freebsd-questions@freebsd.org Date: Friday, September 26, 2008, 1:19 PM On Sep 26, 2008, at 6:51 AM, john seth wrote: > I want to know whether there is facility for mobile DDR RAM, so =20 > that we can switch of a bank(s) without loosing the data in other =20 > bank(s).. Swapping RAM without taking down the system is feature or capability =20 of high-end hardware like Sun Enterprise xx00 and Tandem "non-stop" =20 minis. I don't know of any systems for under a ~6-figure price which =20 has that...
