Mechanical Shock due to suddenly applied forces, or abrupt change in motion produced by handling, transportation or field operation may disturb operating characteristics, particularly if the shock pulses are repetitive. This is a destructive test intended for device qualification.This document also replaces JESD22-B104. Committee(s): JC-14, JC-14.1 Free download. Registration or login required.
LRDIMM DDR3 MEMORY BUFFER (MB)	JESD82-30	Oct 2014
The Load Reduced DIMM (LRDIMM) Memory Buffer (MB) supports DDR3 SDRAM main memory. The Memory Buffer allows buffering of memory traffic to support large memory capacities. Unlike DDR3 Register Buffer (SSTE32882), which only buffers Command, Address, Control and Clock, the LRDIMM Memory Buffer also buffers the Data (DQ) interface between the Memory Controller and the DRAM components. The Memory Buffer interface is responsible for memory requests to and from the local DIMM. LRDIMM provides a high memory bandwidth, large capacity channel solution for DDR3 main memory systems. LRDIMM uses commodity DRAMs isolated from the channel behind the Memory Buffer on the DIMM. Committee(s): JC-40, JC-40.4 Free download. Registration or login required.
