This project shows the memory read operation in 8051. In this circuit the
contents of the memory location from 0000 to 000F is read and the value
displayed in the 7-Segment Display.
The circuit contains an 8051 chip, 7-Segment displays, Latch, Binary to 7-Segment
Decoder and 128K x 8-Bit CMOS One Time PROM. Ports P0 and P2 of 8051 are used
for memory addressing while Port P1 is used as the output port.
The address of memory is send to PROM via latch from the address lines of 8051.
The contents of this location are read and send to the data lines. This data
appears at the output in
