摘要： Methods of setting wordline up-level voltage in as-fabricated SRAM. In one example, the method includes determining the relative speed, or strength, of 1) the combination of the pass-gate and pull-down devices and 2) the pull-up devices in the bitcells of the SRAM. These relative strengths are then used to adjust the wordline up-level voltage, if needed, to decrease the likelihood of the SRAM experiencing a stability failure. Corresponding systems are provided for determining the relative strengths of the devices of interest, for determining the amount of up-level voltage adjustment needed, and for selecting and setting the up-level voltage.

摘要： A memory is provided which can be operated at an active rate of power consumption in an active operational mode and at a predetermined reduced rate of power consumption in a standby operational mode. The memory includes a current generating circuit which is operable to supply a predetermined magnitude of current to a sample power supply input terminal of a sample memory cell representative of memory cells of the memory, the predetermined magnitude of current corresponding to the predetermined reduced rate of power consumption. A voltage follower circuit is operable to output a standby voltage level equal to a voltage level at the sample power supply input terminal when the predetermined magnitude of current is supplied thereto. A memory cell array of the memory is operable to store data. In the standby operational mode, a switching circuit is operable to supply power at the standby voltage level to a power supply input terminal of the memory cell array. This permits data to remain stored in the memory during the standby mode. During an active operational mode, the switching circuit is operable to connect the power supply input terminal at the power supply to supply power at the active voltage level to the memory cell array. During the active operational mode, data can be stored into the memory cell array and retrieved from the memory cell array.

摘要： A method for implementing a self-timed, read to write operation in a memory storage device. In an exemplary embodiment, the method includes capturing a read address during a first half of a current clock cycle, and commencing a read operation so as to read data corresponding to the captured read address onto a pair of bit lines. A write operation is commenced for the current clock cycle so as to cause write data to appear on the pair of bit lines as soon as the read data from the captured read address is amplified by a sense amplifier, wherein the write operation uses a previous write address captured during a preceding clock cycle. A current write address is captured during a second half of the current clock cycle, said current write address used for a write operation implemented during a subsequent clock cycle, wherein the write operation for the current clock cycle is timed independent of the current write address captured during said second half of the current clock cycle.
