Description

SEPTEMBER 2022 The IS43/46LR16128B/32640B is 2,147,483,648 bits CMOS Mobile Double Data Rate Synchronous DRAM organized as 4 banks of 128Meg words of 16bits or 64Meg words of 32bits.

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) - 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 data strobe per byte of data (DQS)
  • DM for write masking only
