Datasheet Summary
512Mb: x4, x8, x16 DDR SDRAM
DOUBLE DATA RATE (DDR) SDRAM
Features
- PC2100, PC2700 and PC3200 patible
- VDD = +2.5V ±0.2V, VDDQ = +2.5V ±0.2V (For
- 6A & 75A)
- VDD = +2.6V ±0.1V, VDDQ = +2.6V ±0.1V (For -5B)
- Bi-directional data strobe (DQS) transmitted/ received with data, i.e. source-synchronous data capture (x16 has two: LDQS and UDQS
- one per byte)
- Internal, pipelined double-data-rate (DDR) architecture; two data accesses per clock cycle
- Differential clock inputs (CK and CK#)
- mands entered on each positive CK edge
- DQS edge-aligned with data for READs; center-aligned with data for WRITEs
- DLL to align DQ and DQS transitions with CK
- Four internal banks for concurrent...
