EBE21UE8ABDA - 2GB DDR2 SDRAM SO-DIMM

Datasheet Summary

Description

Pin name A0 to A13 A10 (AP) BA0, BA1, BA2 DQ0 to DQ63 /RAS /CAS /WE /CS0, /CS1 CKE0, CKE1 CK0, CK1 /CK0, /CK1 DQS0 to DQS7, /DQS0 to /DQS7 DM0 to DM7 SCL SDA SA0, SA1 VDD VDDSPD VREF VSS ODT0, ODT1 NC Function Address input Row address Column address Auto precharge Bank select address Data input/out

Features

  • Double-data-rate architecture; two data transfers per clock cycle.
  • The high-speed data transfer is realized by the 4 bits prefetch pipelined architecture.
  • Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for capturing data at the receiver.
  • DQS is edge-aligned with data for READs; centeraligned with data for WRITEs.
  • Differential clock inputs (CK and /CK).
  • DLL aligns DQ and DQS transitions with CK transi.
