Hi..
      i wanna use sram instead of Vram in my project ... according t
my knowledge vram is same as sram but its dual port...........as fo
display its needed to read and write at same time fastly ...so use

Run the SRAM interface twice as fast and interleave access between
what's writing to it and what's reading from it.

DDR SRAM interfaces are quite fast these days.
