ABSTRACT:
A separate program power input is provided to a programmable logic array's memory to permit it to be programmed independently of printed circuit board power. Means are provided to isolate the program power input from the array's programmable logic circuit. Means are further provided to isolate the memory from the programmable logic circuit. The program power is not connected directly or indirectly to the programmable logic circuit thereby permitting the use of low-power devices to program the memory without connecting the printed circuit board to a power supply.
