Description
The
PD4564441, 4564841, 4564163 are high-speed 67,108,864-bit synchronous dynamic random-access
memories, organized as 4,194,304

bank), respectively.
The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture.
All inputs and outputs are synchronized with the positive edge of the clock.
The synchronous DRAMs are compatible with Low Voltage TTL (LVTTL).
These products are packaged in 54-pin TSOP (II).
Features
Fully Synchronous Dynamic RAM, with all signals referenced to a positive clock edge
Pulsed interface
Possible to assert random column address in every cycle
Quad internal banks controlled by A12 and A13 (Bank Select)
Byte control (
16) by LDQM and UDQM
Programmable Wrap sequence (Sequential / Interleave)
Programmable burst length (1, 2, 4, 8 and full page)
Programmable /CAS latency (2 and 3)
Automatic precharge and controlled precharge
CBR (auto) refresh and self refresh
