    摘要: A heterogeneous cache structure provides several memory cells into different ways each associated with different minimum voltages below which the memory cells produce substantial state errors. Reduced voltage operation of the cache may be accompanied by deactivating different ways according to the voltage reduction. The differentiation between the memory cells in the ways may be implemented by devoting different amounts of integrated circuit area to each memory cell either by changing the size of the transistors comprising the memory cell or devoting additional transistors to each memory cell in the form of shared error correcting codes or backup memory cells.

    摘要: The number of power-gating transistors on an integrated circuit used for power reduction in a sleep mode is controlled during a wake state to adjust the current flow and hence voltage drop across the power-gating transistors as a function of aging of these transistors and/or a function of temperature of the integrated circuit. In this way, the supply voltage to the integrated circuit may be better tailored to minimize current leakage when the integrated circuit is young or operating at low temperatures.

    摘要: A memory system having a selectable configuration for sense amplifiers is included. The memory system can include bit cells and a switch module coupled to the bit cell and to a first portion of a sense amplifier. The switch module can connect, disconnect or cross couple the bit cell to the sense amplifier based on a test for the input offset voltage of first portion of the sense amplifier. A similar configuration can be implemented by a second portion of the sense amplifier. The system can also include a programmer module to configure a setting of the switch module and can include a column select module to couple the bit cells to the sense amplifiers based on what column of bit cell is to be read. Other embodiments are also disclosed.
