We are using cypress CY62157EV30 SRAM, connected on external bus interface of our arm controller.

We are using 16 bit data bus and complete address bus.

While debuging we found that for 16 bit interface mode, data write sucessfuly but

couldn't read back data content at same location and in waveform it shown that addresss

pin A0 always low. We couldn't find exact reason for this problem. Can any one help for this issue.

Hi Raviraj,

Can you share the schematics of the SRAM part with us.

Can you also share the write and read waveforms with us for debugging.

Can you let us know as to how many devices are showing this behavior.

Thanks and Regards,

Pradipta.
