APPENDIX 4: ITC CASES INVOLVING THE
EPROM TEST (171)
The
EPROM encoder used to generate the binary pattern can be set to develop a 12-bit parallel code, the binary state of which corresponds to either the digital inputs connected to ground or to the supply voltage.
Unlike an
EPROM, which requires a separate UV eraser and programmer that can take more than 30 minutes to erase and reprogram, an MTP device can be electrically erased and reprogrammed at least 1,000 times in a few seconds using the same programmer.
imposed anti-dumping duties on Japanese DRAMs and
EPROMs and later negotiated a comprehensive agreement to end dumping and open the Japanese market.
Multiple equations of state and calculation algorithms to API, AGA and ISO standards are programmed into the flow computers using
EPROM technology.

1971: Dov Frohman, an Intel engineer from Israel, invents the
EPROM chip, which retains its memory even when the power is turned off.
It incorporates 36 I/Os (four of them selectable), eight counters, four step counters, four digital and four analog timers, and an 800-instruction memory in RAM, EEPROM, or
EPROM. The unit operates on 24-v d-c power and has a reaction (throughput) time of under 2 millisec.
Intel Corporation invented the first commercial microprocessor in 1971 and introduced the dynamic random-access memory (DRAM) chip, the erasable programmable read-only memory (
EPROM) chip, and the math coprocessor.
The Japanese share of the European
EPROM chip market rose from 60% in 1984 to 78% in 1986 (Paltrow, 1987).
Furthermore, in order for the students to experience the complete board-level software design cycle, they write 8085 code to perform a certain task, assemble it, and burn the resulting hexadecimal code into an
EPROM. This memory chip is then added to the 8085-based microcomputer board.
The paper documents the processes leading Intel Corporation to exit from dynamic random access memory (DRAM) design and manufacturing in 1984-1985, to halt capacity expansion for erasable programmable read only memory (
EPROM) manufacturing in 1991, and to transform itself from a "memory" company into a "microcomputer" company.
