1. An acronym for Electrically PROM, or Electrically Programmable Read-Only Memory. Similar to the technology used in standard EPROM and PROM memory devices. Commonly used in both SPLD and CPLD devices. EPROM cells are electrically programmed in a device programmer. Some EPROM-based devices are erasable using ultra-violet (UV) light if they are in a windowed package. However, most EPROM-based SPLD/CPLDs are in low-cost plastic packaging for production. Plastic packages cannot be UV erased.

2. An acronym for Erasable PROM, or Erasable Programmable Read-Only Memory. This form of device is cleaned (de-programmed) by UV (ultraviolet) light in a device called a PROM eraser.
