IS43LR16128B Product details

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.This product uses a double-data-rate architecture to achieve high-speed operation.The Data Input/ Output signals are transmitted on a 16-bit or 32-bit bus.The double data rate architecture is essentially a 2N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O p

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.
