Hi,
We have tried to read/write data from/to SRAM (AS7C4096) using a tri-state buffer to drive data bus but we are not being able to manage this task. Whenever we try to read data from the memory we obtain the value 0x0000 although the memory word has been loaded with a different pattern. Similarly, when we write data the final value in the memory word is 0x0000 regardless of the value we drive into the data bus.
Has anybody any idea about this? What are we doing wrong?
Thanks a lot
