Leakage measurement systems

摘要

Described examples include leakage measurement systems and methods for measuring leakage current between a word line at a boosted voltage and a word line at a supply voltage. The boosted voltage may be generated by charge pump circuitry. Examples of leakage measurement systems described herein may be included in memory devices.

1. An apparatus, comprising:
a current source configured to be coupled between a supply voltage and a reference voltage, wherein the current source is configured to provide a reference current to a first word line; and a comparator having a first input configured to receive the supply voltage and a second input coupled to the first word line, wherein the comparator is configured to generate a signal indicative of a comparison between the supply voltage and a voltage on the first word line.
