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...
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...

Major difference between DDR4 and DDR3 are: 1. EEPROM size has been increased to 512 bytes. Actual used bytes are 384 bytes. 2. SPD codes are divided into 3 sections: Byte 0 – 127, Byte 128 – 255, and Byte 256 – 383.

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...
Thus my question why their is so much difference in board performance at low cpu frequency? Is this due to LPDDR2? Both LPDDR2 and DDR3L are 400MHz. ラベル: i.MX6UL Linux Yocto Project 返信 1 返信 10-16-201604:28 PM 1,394件の閲覧回数 ...
My custom board which is based on T1040RDB, has DDR3L module MT4KTF25664HZ-1G6E1. This DDR is wroking properly at clock 400 MHz (800 MT/s data rate) while giving error once the clock goes above 400 MHz. ideally DDR should work upto 1600 MT/s. DDR at 400 MHz: U-Boot 2014....
