I've seriously contemplated making my own matching
memory expansion module
for my VXL/30 A500 cpu accelerator. Fairly complicated because I have to
create a DRAM controller. Thinking FGPA w/ a pre-made memory controller
core.
Something I could never understand: Why not using SRAM?
We have tens of megabytes of SRAM today for cheap - useless pentium
cache memory. And even SRAM chips, I have a 2MByte chip that costs almost
nothing. Why all the hassle of using slow and refresh-dependent DRAM if SRAM
is so easy to use?!
