EOL Notification for 3600 Series Spare 4MB DRAM SIMMs EOL

Memory Product Number	Description	Recommended Replacement
MEM3620-4D=	4MB DRAM SIMM for the Cisco 3620	8MB DRAM SIMMs or above (MEM3620-8D=)
MEM3640-2X4D=	8MB DRAM for the Cisco 3640 (2x4MB DRAM SIMMs)	2 8MB DRAM SIMMs (MEM3640-2X8D=)

Note: Due to an increase in Cisco IOS image sizes, 4MB DRAM SIMMs are no longer recommended for a Cisco 3600 Series router memory upgrade. The minimum amount of memory recommended when upgrading a router in the field is 8MB DRAM SIMMs. The Cisco 3640 requires memory upgrade in SIMM pairs, so two 8MB SIMMs are required.
