It is a 4 bit RAM
It is tested with 4 inputs, the clock, the write enable input and the 4-bit input data, the output is 4 bits as well.
The chip may need a Microcontroller, Raspberry, Arduino or FPGA for data inputs and memory addresses or 8 switches can be placed for data inputs and memory addresses.
| # | Input | Output | Bidirectional |
