    4 bit can only have 16 combinations. "A-Z" can hardly be regarded as 4 bit data. If you store them as ASCII, it would be 4 x 8-bit data.

    You can store them in static RAM like 2114 or 6116. in dynamic ram like 4164 or the memory stick in PC, in flash memory like SD ram or pen drive, or in the ram/flash/eeprom inside an mcu like 16F887.......etc, etc

    Or you can store them in 32 D flip flops.

    Two address bit with data width of 8 bit is enough to store "VEAD".

    What kind of example do you need ? Do you want to construct a memory circuit that would store 4 characters in ascii?

    How are you going to store the text characters
    (I.e., from a micro controller)?
    How are you going to read them?
    How are you going to input the characters ?
    Are they going to change?
    Where are you displaying them?

    The devil is in the details.
