1Gb (8M×8Bank×16) Double DATA RATE 2 SDRAM
Features
Description
JEDEC Standard VDD/VDDQ=1.8V ± 0.1V. All inputs and outputs are compatible with SSTL_18 interface. Fully differential clock inputs (CK,/CK) operation. 8 Banks Posted CAS Burst Length: 4 and 8. Programmable CAS Latency (CL): 3, 4 and 5. Programmable Additive Latency (AL):
0, 1, 2, 3 and 4. Write Latency (WL) =Read Latency (RL) -1. Read Latency (RL) = Programmable Additive
Latency (AL) + CAS Latency (CL) Bi-directional Differential Data Strobe (DQS). Data inputs on DQS centers when write. Data outputs on DQS, /DQS edges when read. On chip DLL align DQ, DQS and /DQS transition
with CK transition. DM mask write data-in at the both rising and falling
edges of the data strobe. Sequential & Interleaved Burst type available. Off-Chip Driver (OCD) Impedance Adjustment On Die Termination (ODT) Auto Refresh and Self Refresh 8,1...
