A3S12D40ETP Overview
Description
A3S12D30ETP is a 4-bank x 16,777,216-word x 8-bit, A3S12D40ETP is a 4-bank x 8,388,608-word x 16-bit, double data rate synchronous DRAM, with SSTL_2 interface. All control and address signals are referenced to the rising edge of CLK.
Key Features
- Vdd=Vddq=2.6V+0.1V (for speed grade -5)
- Double data rate architecture; two data transfers per clock cycle
- Bidirectional, data strobe (DQS) is transmitted/received with data
- Differential clock inputs (CLK and /CLK)
- DLL aligns DQ and DQS transitions with CLK transitions edges of DQS
- Commands entered on each positive CLK edge
- data and data mask referenced to both edges of DQS
- Four internal banks for concurrent opertation
- 4 bank operation controlled by BA0, BA1 (Bank Address)
- /CAS latency- 2.0/2.5/3.0 (programmable)
