Assignee: STMICROELECTRONICS INTERNATIONAL N.V.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The integrated circuit die of claim 1, wherein the leakage detector circuit is configured to detect excess leakage within row decoders of the selected one of the memory sectors by operating to:
a) deselect all word lines within the memory array of the selected one of the memory sectors;
b) set the variable current to have a magnitude that is within a threshold of zero;
c) increase the variable current by a given amount, in response to the copy voltage being greater than the gate voltage, and wait a given period of time;
d) when the increase in the variable current by the given amount results in the copy voltage becoming less than the gate voltage, assert the leakage detection signal to thereby indicate excess leakage within the row decoders of the selected one of the memory sectors; and
e) when the increase in the variable current by the given amount does not result in the copy voltage becoming less than the gate voltage, return to c).
