IS42VS16400L - 1 Meg Bits x 16 Bits x 4 Banks (64-MBIT) SYNCHRONOUS DYNAMIC RAM

Description

The 64Mb SDRAM is a high speed CMOS, dynamic random-access memory designed to operate in 1.8V memory systems containing 67,108,864 bits.

InterNally configured as a quad-bank DRAM with a synchronous interface.

Each 16,777,216-bit bank is organized as 4,096 rows by 256 columns by 16 bits.

Features

  • Clock frequency: 133 MHz.
  • Fully synchronous; all signals referenced to a positive clock edge.
  • Internal bank for hiding row access/precharge.
  • Single 1.8V power supply.
  • LVTTL interface.
  • Programmable burst length.
  • (1, 2, 4, 8, full page).
  • Programmable burst sequence: Sequential/Interleave.
  • Self refresh modes.
  • Auto refresh (CBR).
  • 4096 refresh cycles every 64 ms (Com, Ind, A1 grade) or 16.
