Memory Configurations: JESD21-C

JESD21-C, JEDEC Configurations for Solid State Memories, is a compilation of some 3000 pages of all memory device standards for solid state memory including DIMM, DRAM, SDRAM, MCP, PROM, and others from September 1989 to present.  

The JEDEC JC-42 Committee on RAM Memory and its Subcommittees, JC-45 Committee on Memory Modules and its Subcommittees and the JC-63 Committee on Multi Chip Packages develop the standards in JESD21-C and are responsible for updating the publication.

An annual updating service for JESD21 is available by subscription. Subscribers receive periodic electronic updates for replacement or insertion into the hard copy JESD21-C.

A complete hard copy of JESD21-C is available for purchase. The hard copy comes in two 3” wide 3-ring binders so that future updates can be added with ease.
