Ten,

I read the DRDRAM 64/72 Mbit spec, and it contains the following info.

You can keep 16 rows open at a time, and each row is 1K- providing a total of 16K hittable addresses. Compared to a 2MB L3, it is safe to expect the hit rates to be much lower. For many apps, you would be better off precharging after each access.

A lot of people thought that SDRAM would provide a big performance boost over EDO because of the ability to keep pages open, but they were sorely disappointed by reality.
