HMT42GR7CMR4C - DDR3 SDRAM Registered DIMM

Download the HMT42GR7CMR4C datasheet PDF. This datasheet also covers the HMT325R7CFR8C variant, as both devices belong to the same ddr3 sdram registered dimm family and are provided as variant models within a single manufacturer datasheet.

General Description

Registered DDR3 SDRAM DIMMs (Registered Double Data Rate Synchronous DRAM Dual In-Line Memory Modules) are low power, high-speed operation memory modules that use DDR3 SDRAM devices.

Key Features

  • Power Supply: VDD=1.5V (1.425V to 1.575V) VDDQ = 1.5V (1.425V to 1.575V) VDDSPD=3.0V to 3.6V Functionality and operations comply with the DDR3 SDRAM datasheet 8 internal banks Data transfer rates: PC3-14900, PC3-12800, PC3-10600, PC3-8500 Bi-Directional Differential Data Strobe 8 bit pre-fetch Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop) Supports ECC err.
