DESCRIPTION
ValueRAM’s KVR16LR11D4K3/48 is a kit of three 2G x 72-bit
(16GB) DDR3L-1600 CL11 SDRAM (Synchronous DRAM),
registered w/parity, low voltage, 2Rx4 ECC, memory modules,
based on thirty-six 1G x 4-bit FBGA components per module.
Total kit capacity is 48GB. The SPDs are programmed to
JEDEC standard latency DDR3-1600 timing of 11-11-11 at
1.35V or 1.5V. Each 240-pin DIMM uses gold contact fingers.

The electrical and mechanical specifications are as follows:

FEATURES
• JEDEC standard 1.35V (1.28V ~ 1.45V) and 1.5V (1.425V ~
1.575V) Power Supply
• VDDQ = 1.35V (1.28V ~ 1.45V) and 1.5V (1.425V ~ 1.575V)
• 800MHz fCK for 1600Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 11, 10, 9, 8, 7, 6
• Programmable Additive Latency: 0, CL – 2, or CL – 1 clock
• 8-bit pre-fetch
• Burst Length: 8 (Interleave without any limit, sequential with
starting address “000” only), 4 with tCCD = 4 which does not
allow seamless read or write [either on the fly using A12 or
MRS]
• Bi-directional Differential Data Strobe
• Internal(self) calibration : Internal self calibration through ZQ
pin (RZQ : 240 ohm ± 1%)
• On Die Termination using ODT pin
• On-DIMM thermal sensor (Grade B)
• Average Refresh Period 7.8us at lower than TCASE 85°C,
3.9us at 85°C < TCASE < 95°C
• Asynchronous Reset
• PCB : Height 1.180” (30.00mm), double sided component
