Latest Patents

One of Tooher's latest patents is the SRAM leakage reduction circuit. This invention provides a method and system for maintaining a virtual ground node of an SRAM memory array at a minimum level sufficient for data retention. The circuit can maintain the virtual ground node at a virtual ground reference voltage of V−(1.5*V), or maintain 1.5*V across the memory cells. Here, V represents the threshold voltage of an SRAM memory cell transistor, while V is a positive supply voltage. By tracking the V of the memory cell transistors in the SRAM array, the circuit effectively reduces leakage current while maintaining data integrity. Additionally, a threshold voltage reference circuit can include one or more memory cell transistors in parallel or a specially wired memory cell to track the memory cell transistor threshold voltage. The value of the virtual ground reference voltage can be based on a ratio of feedback chain elements in a multiplier circuit.
