EDD2508AKTA-5-E Overview
The EDD2508AKTA-5 is a 256M bits DDR SDRAM organized as 8,388,608 words × 8 bits × 4 banks. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 2 bits prefetch-pipelined architecture.
EDD2508AKTA-5-E Key Features
- Power supply: VDD, VDDQ = 2.6V ± 0.1V
- Data rate: 400Mbps (max.)
- Double Data Rate architecture; two data transfers per clock cycle
- Bi-directional data strobe (DQS) is transmitted /received with data for capturing data at the receiver
- Data inputs, outputs, and DM are synchronized with DQS
- 4 internal banks for concurrent operation
- 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
- mands entered on each positive CK edge; data and data mask referenced to both edges of DQS
