Abstract
Official abstract text for this publication.
An integrated circuit is disclosed. The integrated circuit includes a plurality of bit-cells arranged to store data. The integrated circuit also includes a sensor configured to generate an output for determining whether the bit-cells are operating at a process corner. The sensor comprises the same circuitry as the bit-cells.
First claim
Opening claim text (preview).
What is claimed is: 1. An integrated circuit, comprising: a plurality of bit-cells arranged to store data; and a sensor configured to generate an output for determining whether the bit-cells are operating at a process corner, wherein the sensor comprises two cross-coupled inverters, each of the cross-coupled inverters comprising a p-channel pull-up transistor and an n-channel pull-down transistor, a first access transistor configured to connect a first bit-line to an input of…
