The 8721 PLA, or programmable logic array, was one of the chips that had to be invented to make the Commodore 128, the last of the 8-bit computers that formed the leading edge of the early PC ...

The first practical programmable logic chips, known as PLAs (programmable logic arrays), became available in the mid 1970s. Things really took off though when MMI introduced a simplified series of ...

Californian startup Adaptive Silicon has publicly unveiled the design that the company will use to bring its own form of programmable logic to ASICs. In a break from traditional programmable-logic ...

Abstract: The Programmable Logic Array (PLA) macro is a physical structure which simplifies LSI chip design while yielding high density and good performance. In addition, the inherent order and ...

Abstract: This paper presents a programmable logic array (PLA) layered structure composed of single-electron tunneling transistor (SET) devices. In this array bits of information are represented by ...

This optical PLA leverages parallel spectrum modulation to achieve an 8-input system, greatly enhancing the scope of optical logic operations. Demonstration and application of large-scale optical ...

As reported in Advanced Photonics, they developed a large-scale optical programmable logic array (PLA) capable of handling more complex computations. This new optical PLA uses parallel spectrum ...

Blurring that line slightly is gate array logic (GAL). These devices were a preceursor to the FPGA, with a much simpler structure, and usually in those days UV-erasable in the same manner as an EPROM.
