support for digital SRAM based IMC

[1ucky2]

Thank you for your code，it is really good！
And does this repo support for digital SRAM based IMC？I mean add AND,NOR etc gates into the cell of SRAM？
I reviewed your doc and I think this two modes are different from what I said above.
“With various device technologies, the chip could operate in different modes, such as digital sequential
(row-by-row) read-out for near-memory computing, or analog parallel read-out for in-memory computing.
In the simulator, the parameters of synaptic devices and synaptic array modes will be instantiated in
param.cpp. ”

Thank you very much!
