Each memory cell stores 16 bits of data Address and value to write must be sent in on the same tick, mode bit 1 tick later Mode bit must be 1-tick long ; 0 : read mode, 1 : write mode Address must be 1-tick long Input : (on the 3 leftmost electric poles) - address - data to write - mode bit Output : (on rightmost electric pole) - data read Each constant combinator must output the address of its memory cell with -1 intensity, using signals from 0 to F Cells must be copy-pasted downwards
