Cisco MEM3640-2X8D= 16MB DRAM Memory Upgrade | 2x8MB SIMMs Expansion for Cisco 3640 Router | Black

Brand:

Cisco

Specifications

Product Description

The Cisco MEM3640-2X8D= is a 16MB DRAM expansion memory kit designed for the Cisco 3640 Router. It includes two 8MB SIMMs (Single Inline Memory Modules) that work together to expand the router’s total DRAM capacity by 16MB. This upgrade enables the router to handle basic network tasks and enhances its ability to run small-scale configurations, simple access control lists (ACLs), and limited routing protocols.
