General Description

The IS43/46LR16640C/32320C is 1,073,741,824 bits CMOS Mobile Double Data Rate Synchronous DRAM organized as 4 banks of 64Meg words of 16bits or 32Meg words of 32bits.

This product uses a double-data-rate architecture to achieve high-speed operation.

Overview

IS43/46LR32320C IS43/46LR16640C 1Gb (x16, x32) Mobile DDR SDRAM.

Key Features

  • JEDEC standard 1.8V power supply.
  • VDD = 1.8V, VDDQ = 1.8V.
  • Four internal banks for concurrent operation.
  • MRS cycle with address key programs - CAS latency 2, 3 (clock) - Burst length (2, 4, 8, 16) - Burst type (sequential & interleave).
  • Fully differential clock inputs (CK, /CK).
  • All inputs except data & DM are sampled at the rising edge of the system clock.
  • Data I/O transaction on both edges of data strobe.
  • Bidirectional d.
