... ELECTRICALLY ERASABLE EPROM GENERAL DESCRIPTION The W27E512 is a high speed, low power Electrically Erasable and Programmable Read Only Memory organized as 65536 8 bits that operates on a single 5 volt power supply. The W27E512 provides an electrical chip erase function. FEATURES High speed access time: 45/55/70/90/120/150 nS (max ...

... The erase operation is the only way to change data from "0" to "1." Unlike conventional UVEPROMs, which use ultraviolet light to erase the contents of the entire chip (a procedure that requires up to half an hour), the W27E512 uses electrical erasure. Generally, the chip can be erased within 100 mS by using an EPROM writer with a special erase algorithm. ...

... OE /V Two-line Output Control Since EPROMs are often used in large memory arrays, the W27E512 provides two control inputs for multiple memory connections. Two-line control provides for lowest possible memory power dissipation and ensures that data bus contention will not occur. ...
