What is the difference between DDR3 and DDR3L? DDR3L is a low-voltage variant of DDR3 random-access memory (RAM). It operates at a lower voltage (1.35V) compared to the standard DDR3 voltage (1.5V). DDR3L is often used in laptops and mobile devices to improve energy efficiency and...
DDR概念理解 的2倍; IO总线上一次预取2、4、8、16bits的数据,则IO总线频率是记忆存储芯片工作频率的N倍;DDR3L:在DDR3的基础上电压降低:1.35–1.3LPDDR3:JEDEC...一般只是内置在SOC中作为cache使用; 目前常见的运行内存都是基于SDRAM基础上发展而来:SDRAM–DDR–DDR2–DDR3– ...
SSTL:全称Stub Series Terminated Logic,短截线串联端接逻辑; DIFF_SSTL:全称Difference Stub Series Terminated Logic,差分短截线串联端接逻辑。 LVCMOS的特点是噪声容限大,速度较SSTL慢;SSTL速度快,通常要匹配合适的端接电阻,常用于高速内存接口如DDR3;DIFF_SSTL则是带有差分功能的SSTL。 DDR3的管脚使用的是SSTL或...

If we can design with one chip then does it mean the layout is in flyby topology and we need to include termination resistors?2, Is there any difference between layout requirements for ddr3 and ddr3L other than the voltage requirement for imx6 ?Regards,Sreedhar Solved! Go to Solution. ...
Solved: I have 2 boards that share the same PCB. The only difference is that one board is populated w/ DDR3L memory, and the other is populated w/

I’ve prefaced our DDR3L vs DDR4 testing with all this as a response to ‘large CL = bad’. Actually, you have to compare both numbers. Now that we have a platform that runs both, and we were able to source a beta DDR3L/DDR4 combination motherboard to test them on, w...
