SRAM vs SDRAM

I've found the SDRAM controller performance to be pretty awful. Given

the logic area it occupies and its performance, I no longer consider it a

viable alternative for many new designs.

I've switched to PSRAM (pseudo SRAM) for new designs. It eliminates

the SDRAM controller and it performs better. The cost is

very attractive ... the expense is the number of pins you must use.
