simple programmable logic device (PLD) (SPLD)
Programmable Logic Devices(PLD) are divided into Field Programmable Logic Devices (FPLD), Simple Programmable Logic Devices (SPLD) and Complex Programmable Logic Devices ( CPLD), which can be programmed at the customer's site.
Simple Programmable Logic Devices have a simple logic structure. They consist of an AND gate feeding an OR gate. The difference is whether one or the other logic or both logics are programmable. SPLDs can be programmed using a variety of techniques. Via the melting technique, where a micro- fuse is melted by current flow and a logic is broken in the process, via the fabrication of a logic, or via the memory-based techniques used in Programmable Logic Devices (PLD).
