dual port RAM

Hi,

Let's say that I need at least 64KB dual port RAM... Any ideea how to implement ? At this moment the timming of it is not important.

Cheers !

Not clear what you want.

To implement your own dual-port memory? Then this question for FPGA or ASIC forum, not Microcontrollers.

If you need 64K dual-port to use with microcontroller, then just select one from Cypress or IDT. They have even higher capacities.

Or maybe you want to implement dual-port memory with uC and usual static RAM?

Hi,

Yes I want to implement dual port RAM with uC & static RAM.

Cheers !

Then you just have to implement simple arbiter in uC, which receives Write/Read requests from two sources and provide control signals for memory and tri-state registers between Address/Data lines of memory and two sources. You even don't have to lead address/data lines of static memory and two sources to uC, so uC with 8 I/O pins should be enough for this task.
