General Description

The IS43/46LR16320B is a 536,870,912 bits CMOS Mobile Double Data Rate Synchronous DRAM organized as 4 banks of 8,388,608 words x 16 bits.

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

The Data Input/ Output signals are transmitted on a 16bit bus.

Overview

IS43LR16320B, IS46LR16320B 8M x 16Bits x 4Banks 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.
