3-2 Cache Memory

Since the second level cache has been embedded into the Pentium II CPU. You
do not have to take care of either SRAM chips or SRAM modules. The built-in
second level cache in the Pentium II yields much higher performance than the
external ones. The cache size in the Pentium II CPU is either 256KB or 512KB.
Normally, for workstation and server applications, the 256KB version is good
enough. However, i f your system is for heavy duty applications, the 512kB
version will help a lot. Specifically for our Pentium II based SBC, the Pentium II
has another version provide much better data security if combined with the
DRAM ECC, please check with your vendor for various Pentium II models.
The level 2 cache of the Peak 6320A is built in the Celeron/Coppermine current
Celerons have 128 KB on die L2 Cache which is very fast because it's running at
the CPU speed. Future Celerons/Coppermine might be upgraded to 256 KB L2
Cache.
