Today I have finished the Memory Unit.
It can store 64KB of memory (16 Address bits, 8 Data bits).

Its made out of 2x 32KB SRAM chips and 1x Hex Inverter Chip (to control the selection of one of the two chips and the Write signal).

An Arduino with 2x 8bit Shift Registers is used to Read/ Write the SRAM.
