Memory - Configuration Proms for FPGAs

Configuration PROMs (programmable read-only memory) are specialized memory devices that are used to configure the internal logic of an FPGA (field-programmable gate array). An FPGA is a type of programmable logic device that consists of an array of configurable logic blocks and programmable interconnects. The configuration PROM stores the configuration data that determines the specific logic functions and connections of the FPGA. When the FPGA is powered on, it reads the configuration data from the PROM and uses it to configure its internal logic. This allows the user to program the FPGA to implement a wide range of digital circuits and systems, without the need for specialized hardware or knowledge of the FPGA's underlying technology. The specific features and capabilities of a configuration PROM depend on the intended application and the requirements of the FPGA. Some common types of configuration PROMs include serial PROMs (SPROMs), parallel PROMs (PPROMs), and flash memory-based PROMs.
