TI LAUNCHES A NEW EPROM CHIP (OCTOBER 1977)   



The first 2716 EPROM was launched in October 1977 by Texas Instruments.

An EPROM (Erasable Programmable Read Only Memory) can be programmed and then erased enabling it to be re-used about 1000 times. Programming is accomplished through a device called Eprom programmer (or EPROM burner), erasure uses an Ultra Violet light source that shines through a quartz erasing window.

At the time, EPROM's were widely used to store boot-up programs in small systems or saving user's programs in computers that didn't featured tape recorder or floppy drive interface. Two types of EPROM chip were already used in 1977: 2704 (512 bytes) and 2708 (1 KB), but then users and computer manufacturers were requiring higher capacity chips. So came the 2716, wich was able to store 2 KB. The first TMS 2716 is actually a rarity because the chip needed 3 different voltages to run it, which was different than the 2716 Intel's and all others that manufacturers made later. So, TI quickly built a new Intel compatible chip, called it TMS2516 to differenciate it from the first version and sold hundred thousands of pieces.
