Emulation of 'static RAM', which is essentially built from D-type flip-flops.
The principal difference between this and the standard RAM component in CircuitVerse is that all the static RAMs in this project are edge-triggered for write (reading is asynchronous).
The basic building block is the 1x8-bit SRAM circuit - a single byte of memory, built from an 8-bit D-type flip flop.
16 of these are then used in a 4 x 4 grid to build the 16x8-bit SRAM circuit, which now includes the necessary 4-bit address decoding circuitry.
16 of these are then used in a 4 x 4 grid to build the 256x8-bit SRAM circuit.
The pattern could be applied recursively to build, in turn, a 4KB, 64KB, 1MB chip, and so on.
Set both buttons to off (RED). Now reset the sequencer and turn on button 1 and 2 (set to GREEN).
Button 1 controls the data fed to the displays.
OFF = Clear all displays ON = Programmed message
Button 2 controls the clock.
To change the message, dump the core or reset the EEPROM and rewrite the suitable data for the 16-Segment Displays. If the new message contains lesser or more letters/numbers to show, make suitable changes to the Sequencer and change the number of displays used.
