SRAM is datwsheet as in the schematic. Here is code for reading and writing: You have RAM and processor driving the bus simultaneously, e. Last edited by FvM; 11th December at datadheet Rewrite Read and Write functions as follows: I’m beginning to suspect on my memory chip. In this case, the wiring may be a problem, particularly insufficient or too long ground connection between both boards.


Control lines are going thru single wires about 25cm long. Gnd was connected via a longer ribbon cable. When I changed longer ribbon cable and made double connection to gnd all started to work as it should.

Tonight I will write a small program which will read and verify the memory and report failure if any, and leave it over night. So far looks promising.
