Abstract
An apparatus and method for constructing a temperature insensitive memory cell. This temperature insensitive memory cell operates as a static random access memory (SRAM) cell if a particular capacitor and transistor configuration is used. The temperature insensitive memory cell apparatus includes at least one transistor having a current leakage, and at least one capacitor electrically connected to the transistor. The capacitor acts as a load element for the memory cell. The capacitor has a temperature dependent capacitor leakage that tracks the current leakage of transistor as said at least one transistor as the transistor varies with temperature.
