Description
The EDE5104AGSE is a 512M bits DDR2 SDRAM
organized as 33,554,432 words
4 bits
4 banks.
The EDE5108AGSE is a 512M bits DDR2 SDRAM
organized as 16,777,216 words
8 bits
4 banks.
They are packaged in 60-ball FBGA (
BGA
) package.
Features
Power supply: VDD, VDDQ
=
1.8V
0.1V
Double-data-rate architecture: two data transfers per
clock cycle
Bi-directional, differential data strobe (DQS and
/DQS) is transmitted/received with data, to be used in
capturing data at the receiver
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
transitions
Commands entered on each positive CK edge: data
and data mask referenced to both edges of DQS
Four internal banks for concurrent operation
Data mask (DM) for write data
Burst lengths: 4, 8
/CAS Latency (CL): 3, 4, 5
Auto precharge operation for each burst access
Auto refresh and self refresh modes

organization compatible to
4 organization
/DQS, (/RDQS) can be disabled for single-ended
Data Strobe operation.

Notes: 1. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect reliability.
2. Storage temperature is the case surface temperature on the center/top side of the DRAM.
Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
