Sorry, I made a mistake, cache memories are SRAM, not SDRAM. In fact,
they used to have the same part number as usual SRAMs, but are faster.

KI>The biggest headache of using dynamic random access memory (DRAM) is the
KI>refresh.  Unlike static random access memory (SRAM) which requires no
KI>refresh, you have to address the memory within a specified amount of time
KI>(whether you need that location or not at that time) or you lose the data.
KI>They have specific chips that help with the refresh but as a general rule it
KI>is more complicated, and not worth it unless you have a lot of memory and
KI>high volume, because DRAM is cheaper than SRAM.  Most microcontrollers use
KI>SRAM.
