The lowest bank (bank 0) was erasable memory (RAM).
Block II had 32 kilowords of fixed memory and 4 kilowords of erasable memory.
It retained the basic Block I architecture, but increased erasable memory from 1 to 2 kilowords.
EPROM, or erasable programmable read-only memory, is similar to PROM but can be cleared by exposure to ultraviolet light.
Intel said today that it would buy the chips, known as erasable programmable read-only memories, or Eproms, and resell them under its own name in the Japanese market.
The fixed and erasable memory were constructed similarly so the ratio between fixed and erasable memory was variable.
There's only two kilobytes of erasable memory, and they need that for data storage.
Some EPROM (erasable programmable read-only memory) modules are erased by exposure to UV radiation.
An electrically erasable programmable read-only memory EEPROM uses electrical signals to erase memory.
But who makes Intel's erasable, programmable, read-only memories?
