Cisco MEM3620-32U64D-repl enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM3620-32U64D-repl is a memory upgrade module for the Cisco 3620 modular router, taking the router’s DRAM from 32MB to 64MB, supplied as a compatible replacement for the original Cisco part. The 3620 was one of Cisco’s earlier compact modular access routers, and increasing its onboard memory extends how large an IOS feature set, routing table and buffer allocation it can support before running short of working memory.

Upgrade kits of this specification remain the standard way to keep 3620-based deployments running current IOS releases without a full router replacement. As a compatible module rather than an original Cisco-branded part, it is built to the same electrical specification as the genuine Cisco memory it replaces. Tech-Star is UK-based and ships worldwide; confirm compatibility with your specific chassis before ordering.
