The 28F020 adds electrical chip-erasure and reprogramming to familiar EPROM technology. Memory contents can be rewritten: in a test socket; in a PROM-programmer socket; onboard during subassembly test; in-system during final test; and in-system after sale. The 28F020 increases memory flexibility, while contributing to time and cost savings. The 28F020 is a 2048-kilobit nonvolatile memory organized as 262,144 bytes of eight bits.
