摘要:
An SRAM with reduced power consumption comprising N SRAM cells and peripheral circuitry that enables writing and reading any of the N SRAM cells. The number of cells, N, is a whole number. The voltage applied to the N SRAM cells is higher than the voltage applied to the peripheral circuitry.
摘要:
A method for reducing power in an SRAM is achieved by applying a first voltage to all bitlines of a section of the SRAM in standby operation and applying a second voltage to all the bitlines of a section of the SRAM in normal operation. The first voltage is not greater than the second voltage.

According to at least one embodiment, a method comprises measuring drive current of a reference memory cell of a circuit, and determining, based on the measured drive current of the reference memory cell, a drive current to be supplied to a calibration memory cell of the circuit to mimic a defective memory cell. The method further comprises supplying the determined drive current to the calibration memory cell, and using the calibration memory cell to determine strength of a weak write to be utilized by a weak write test for detecting defective memory cells.

A computer system is disclosed that includes a memory, a memory defect map, and a shift encoder. The memory includes a plurality of bits and a plurality of input/output ports for accessing the plurality of bits. The memory defect map specifies positions of defective ones of the plurality of bits. The shift encoder encodes positions of defective ones of the plurality of bits in a shift encoding. The shift encoding includes a shift redundancy record representing positions of transitions between functional bits and defective bits in the memory, and a hints record representing numbers of bits in sets of consecutive defective bits in the memory.
