Cisco 831 memory sizes?

[tsgcisco]

I know there are two 831 routers:

CISCO831-K9

CISCO831-K9-64

My understanding is one has 32 MB versus the second one having 64.

Benefits and reasons for the 64 MB version over the 32 MB version?

The additional DRAM helps ensure that Cisco 831 Series routers will be able to support new versions of Cisco IOS Software that deliver more powerful IP services.
