WebMar 25, 2024 · (Array of Programmable Logic) an array of programmable AND and OR gates on a programmable logic device (PLD). The use of PLAs has ended. In 1970, Texas Instruments developed a mask-programmable IC based on the IBM read-only associative memory or ROAM. This device, the TMS2000, was programmed by altering the metal layer during the production of the IC. The TMS2000 had up to 17 inputs and 18 outputs with 8 JK flip-flops for memory. TI coined the term programmable logic array for this device. A programmable logic array (PLA) has a programmable AND gate array, which links to a progra…
