Programmable Array Logic. Programmable array logic pal is a logic device which has programmable and array and fixed or array. Programmable array logic pal is a type of programmable logic device pld used to realize a particular logical function.
The basic configuration of a pal consists of a programmable and array and followed by a fixed or gate. The inputs in true and complementary form drive an and array which produces implicants which in turn are ored together to form the outputs.

Programmable array logic pal is a commonly used programmable logic device pld.
Because only the and array is programmable it is easier to use but not flexible as compared to programmable logic array pla. Because only the and array is programmable it is easier to use but not flexible as compared to programmable logic array pla. Programmable logic array pla is a fixed architecture logic device with programmable and gates followed by programmable or gates. Programmable array logic pal is a type of programmable logic device pld used to realize a particular logical function.
