简化DRAM控制器设计,DRAM控制器只需要在每个刷新周期向每个Rank发送8192个刷新。根据自身密度决定刷新行数,DRAM控制器发送2个刷新命令之间的间隔为刷新周期的1/8192,定义为TREF1;DRAM芯片执行一个刷新命令的时间取决于DRAM芯片的密度,定义为TREC.因此每个间隔内需要刷新的行数增多,刷新所占的时间比例不断增大。以4Gb D...
A temperature sensing circuit allows a DRAM array to use less power than would normally be possible due to the reduced refresh rate based on the temperature of the DRAM array. The temperature circuit removes the refresh guardbanding on t... CW Tillinghast,MS Cohen,TW Voshell 被引量: 233发表...
Part Number: AM3352 Hi Team, My customer have 3 questions about refresh rate settings for DRAM controller of AM3352. 1. The current setting is reg_refresh_rate
For example, stack position identifiers (SPIDs) are assigned or otherwise determined, and are used by each memory device to make a number of adjustments. In one embodiment, a self-refresh rate of a DRAM is adjusted based on the SPID of that device. In another embodiment, a latency of a...
is provided. A maximum of 8 Refresh commands can be postponed during operation of the LPDDR5 SDRAM, meaning that at no point in time more than a total of 8 Refresh commands are allowed to be postponed and maximum number of pulled-in or postponed REF command is dependent on refresh rate....
