A programmable logic array (PLA) has a programmable AND gate array, which links to a programmable OR gate array, which can then be conditionally complemented to produce an output. A PLA is similar to a ROM concept, however a PLA does not provide full decoding of a variable and does not generate all the minterms as in a ROM.
Programmable Array Logic (PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits that was introduced by Monolithic Memories, Inc. (MMI) in March 1978. [1] MMI obtained a registered trademark on the term PAL for use in "Programmable Semiconductor Logic Circuits".
A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits. The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.
The term commonly refers to devices such as ROMs, PALs, PLAs and GALs. ... (PAL) Generic array logic (GAL) Programmable logic arrays (PLA) Field-programmable logic ...
Technology node 1 μm. A complex programmable logic device ( CPLD ) is a programmable logic device with complexity between that of PALs and FPGAs , and architectural features of both. The main building block of the CPLD is a macrocell , which contains logic implementing disjunctive normal form expressions and more specialized logic operations.

It is one type of read-only memory (ROM). PROMs are used in digital electronic devices to store permanent data, usually low level programs such as firmware or microcode. The key difference from a standard ROM is that the data is written into a ROM during manufacture, while with a PROM the data is programmed into them after manufacture. Thus ...
