-
Description
The W631GG6KB is a 1G bit DDR3 SDRAM, organized as 8,388,608 words x 8 banks x 16 bits. This device achieves high-speed transfer rates up to 1866 Mb/sec/pin for various applications. It is sorted into the following speed grades: -11, -12, 12I, 12A, 12K -15, 15I, 15A, and 15K. The -11 speed grade is compliant with the DDR3-1866(13-13-13) specification. The -12, 12I, 12A, and 12K speed grades are compliant with the DDR3-1600(11-11-11) specification, and the -15, 15I, 15A, and 15K speed grades are compliant with the DDR3-1333(9-9-9) specification. The W631GG6KB is primarily used in integrated circuit (IC) chips and is suitable for various applications.
Specifications and features
- Power Supply: VDD, VDDQ = 1.5V ± 0.075V
- Double Data Rate architecture: two data transfers per clock cycle
- Eight internal banks for concurrent operation
- 8 bit prefetch architecture
- CAS Latency: 6, 7, 8, 9, 10, 11, and 13
- Burst length 8 (BL8) and burst chop 4 (BC4) modes: fixed via mode register (MRS) or selectable On The-Fly (OTF)
- Programmable read burst ordering: interleaved or nibble sequential
- Bi-directional, differential data strobes (DQS and DQS#) are transmitted/received with data
- Edge-aligned with read data and center-aligned with write data
- DLL aligns DQ and DQS transitions with clock
- Differential clock inputs (CK and CK#)
- Commands entered on each positive CK edge, data, and data mask are referenced to both edges of a differential data strobe pair (double data rate)
- Posted CAS with programmable additive latency (AL = 0, CL - 1, and CL - 2) for improved command, address, and data bus efficiency
- Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
- Auto-precharge operation for read and write bursts
- Refresh, Self-Refresh, Auto Self-refresh (ASR), and Partial array self-refresh (PASR)
- Precharged Power Down and Active Power Down
Application Scenarios
