... ELECTRICALLY ERASABLE EPROM GENERAL DESCRIPTION The W27C512 is a high speed, low power Electrically Erasable and Programmable Read Only Memory organized as 65536 provides an electrical chip erase function. FEATURES High speed access time: 45/70/90/120 nS (max.) Read operating current (max.) Erase/Programming operating current 30 mA (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 W27C512 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 W27C512 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. ...
