YouTube CrashCourse #6 "Registers and RAM". Gated Latch. The upper wire is the data input while the lower is write enable.
Set write-enable wire to 1 in order to be able to store data.
Store data (the bit) either 1 or 0 using data-input wire.
Save data in memory by setting write-enable off (that is setting it to 0).
Try!
