32M words × 8 bits × 8 banks (EDJ2108EDBG)  
Package  
Double-data-rate architecture: two data transfers per  
clock cycle  
The high-speed data transfer is realized by the 8 bits  
prefetch pipelined architecture  
Bi-directional differential data strobe (DQS and /DQS)  
is transmitted/received with data for capturing data at  
the receiver  
78-ball FBGA  
Lead-free (RoHS compliant) and Halogen-free  
Power supply: 1.35V (typ.)  
VDD, VDDQ = 1.283V to 1.45V  
DQS is edge-aligned with data for READs; center-  
aligned with data for WRITEs  
Differential clock inputs (CK and /CK)  
DLL aligns DQ and DQS transitions with CK  
Backward compatible for VDD, VDDQ  
transitions  
= 1.5V ± 0.075V  
Commands entered on each positive CK edge; data  
Data rate

1KB page size  
and data mask referenced to both edges of DQS  
Data mask (DM) for write data  
Posted /CAS by programmable additive latency for  
Row address: A0 to A14  
better command and data bus efficiency  
Column address: A0 to A9, A11 (EDJ2104EDBG)  
On-Die Termination (ODT) for better signal quality  
Synchronous ODT  
A0 to A9 (EDJ2108EDBG)  
Eight internal banks for concurrent operation  
Burst lengths (BL): 8 and 4 with Burst Chop (BC)  
Burst type (BT):  
Sequential (8, 4 with BC)  
Interleave (8, 4 with BC)  
/CAS Latency (CL): 5, 6, 7, 8, 9, 10, 11  
/CAS Write Latency (CWL): 5, 6, 7, 8  
Dynamic ODT  
Asynchronous ODT  
Multi Purpose Register (MPR) for pre-defined pattern  
read out  
ZQ calibration for DQ drive and ODT  
Programmable Partial Array Self-Refresh (PASR)  
/RESET pin for Power-up sequence and reset  
Precharge: auto precharge option for each burst  
function

SRT range:  
Normal/extended  
Programmable Output driver impedance control  
Driver strength: RZQ/7, RZQ/6 (RZQ = 240)  
Refresh: auto-refresh, self-refresh  
Refresh cycles  
Average refresh period  
7.8µs at 0°C TC ≤ +85°C  
3.9µs at +85°C < TC ≤ +95°C  
Operating case temperature range
