可编程序逻辑阵列(PLA),做为随机逻辑的通用逻辑元件,用在各种大规模集成化的逻辑装置和机器的控制逻辑电路上。尤其是,用户(逻辑设计者)可以在现場随意编程序的“现場可编程序逻辑阵列”(FPLA),除了过去已出售的品种外,还出现了內部有触发器的用来实现时序电路的FPLA,以及可以固定“或”阵列,只对“与”阵列进 Programmable Logic Arrays (PLAs), which are general purpose logic elements of random logic, are used on control logic circuits of various LSI devices and machines. In particular, the Field Programmable Logic Arrays (FPLA) that users (logic designers) can program at will in the field, in addition to the varieties that have been sold in the past, have internal triggers used to implement timing Circuit FPLA, as well as can be fixed “or” array, only for “and” array into
