Description
The
μ
PD4516421A, 4516821A, 4516161A are high-speed 16,777,216-bit synchronous dynamic random-access

bank), respectively.
The synchronous DRAMs achieve 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).
The synchronous DRAMs are packaged in 44-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
Dual internal banks controlled by A11 (Bank Select)
Programmable burst-length (1, 2, 4, 8, Full Page)
Programmable wrap sequence (Sequential/Interleave)
Programmable CAS latency (2, 3)
Automatic precharge and controlled precharge
CBR (Auto) refresh and self refresh
