Performance differences between EDO DRAM and SDRAM?

If you're talking about EDO simms vs. SDRAM dimms you're comparing 60ns to 7ns RAM. Quite a difference. I'm not sure exactly how that translates in terms of real world performance. Someone with ...

Are there any SDRAM to EDO converters

With the RAM prices the way they are, and the fact that I have to install EDO memory in pairs (it's cheaper to get 2 128MB PC133 DIMMS than 1 64MB EDO SIMM), I was wondering if there's any product ...

SDRAM Controller For Low-end FPGAs

There are very few ‘recent’ FPGAs out there that can be easily soldered. Due to their important number of IOs, they usually come in Ball Grid Array (BGA) packages. The Xilinx Spartan 6 LX9, a TQFP144 ...
