Upgrading Cache Memory

The second-level cache is upgradable from 256 KB to 512 KB. The
system supports both write-back and write-through modes. See the
table below for the possible cache configurations.
Cache Size Data SRAM
256 KB 32 Kb x 8 x 8 pcs
512 KB 64 Kb x 8 x 8 pcs
Follow these steps to install SRAMs:
1. Locate the cache sockets on the system board. See the section
Board Layout.
2. Insert the SRAM chip into socket. Align the straight edge of the
chip with the straight edge of the socket. Also, make sure that
the cut edge of the chip corresponds to the cut edge of the cache
socket. See the figure below.
