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 regularity of ...

The field programmable gate array has always been a different sort of animal in the semiconductor market. While it has evolved from just a bunch of logic gates that can emulate other hardware and ...

Be my PAL The PAL family continued to evolve into the late 1980s, with faster, lower-power devices, including ones that could be reprogrammed. The most complex device type developed was probably the ...

That EPROMs, EEPROMs and kin can be used as programmable logic should probably not come as a major surprise, but [Jimmy] has created a Lisp-based project that makes using these chips as a logic ...

Programmable-logic devices built with Lattice Semiconductor's ispXP (in-system-programmable-expanded-PLD) architecture allow you to combine nonvolatile storage of logic-configuration data with ...

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.

In those days, programmable devices consisted of PALs (programmable array logic devices) and CPLDs (complex programmable logic devices), which were essentially small sets of AND-OR planes with ...
