Hello everyone, I am currently going through various resources on SRAM design focusing on memory clock signal generation. I have found that
most of the existing designs use external clock signal, and some designs use that external clock as a reference for internal clock generation.
Most of the cases this external clk comes from the CPU. In our previous SRAM design, we have used external CLK from CPU, that means, we didn't need to work on CLK circuitry. Now, we want to design an
on-memory CLK for the 32*1024 SRAM with the peripherals. Now, I wanted to seek your guidance on the necessity and feasibility of
generating the clock signal entirely within the SRAM cell itself. Specifically, is it essential to find a method for internal clock
generation within the SRAM? Or I also should follow the conventional approach to design internal clock generation circuit which will be engaged to generate clk for the memory but based on the external reference clk signal? Or Self-Timed (Asynchronous SRAM) approach should
be followed? I would greatly appreciate your insights on this matter.
To be more precise
In our previous design, we controlled the word line, precharge/CLK, read enable, write enable using external signals. How can we control these functions from inside the memory using any block or circuitry that will also allow us to reduce the use of fewer external signals. Could you please help me with this please ?
