DESCRIPTION
M2V28S20TP is organized as 4-bank x 8,388,608-word x 4-bit Synchronous DRAM with LVTTL
interface and M2V28S30TP is organized as 4-bank x 4,194,304-word x 8-bit and M2V28S40TP is organized as
4-bank x 2,097,152-word x 16-bit. All inputs and outputs are referenced to the rising edge of CLK.
M2V28S20TP,M2V28S30TP,M2V28S40TP achieves very high speed data rates up to 133MHz, and is
suitable for main memory or graphic memory in computer systems.
FEATURES

- Max. Clock frequency
- PC133(-6) supports x4/x8 only. And does not support Low-Power (L) version.
- Fully synchronous operation referenced to clock rising edge
- 4-bank operation controlled by BA0,BA1(Bank Address)
- /CAS latency- 2/3 (programmable)
- Burst length- 1/2/4/8/FP (programmable)
- Burst type- Sequential and interleave burst (programmable)
- Byte Control- DQML and DQMU (M2V28S40TP)
- Random column access
- Auto precharge / All bank precharge controlled by A10
- Auto and self refresh
- 4096 refresh cycles /64ms
- LVTTL Interface
