Description	256M SSTL_2 interface DDR SDRAM 143 MHz/133 MHz/125 MHz/100 MHz 4-Mword 16-bit 4-bank/8-Mword 8-bit 4-bank/ 16-Mword 4-bit 4-bank

HM5425401B Overview

The HM5425161B, the HM5425801B and the HM5425401B are the Double Data Rate (DDR) SDRAM devices. Read and write operations are performed at the cross points of the CLK and the CLK. This high speed data transfer is realized by the 2-bit prefetch piplined architecture.

HM5425401B Key Features

Programmable burst sequence  Sequential  Interleave
Start addressing capability  Even and Odd
Programmable CAS latency: 2/2.5
8192 refresh cycles: 7.8 µs (64 ms/8192 cycles)
2 variations of refresh  Auto refresh  Self refresh
