Abstract: Rows of a memory array are segmented into a predetermined number of word line groups. Each row in a word line group has a word line disposed between parallel power supply lines. Each of the power supply lines in a row of a word line group is shared by an adjacent row in the word line group. A row on a boundary of a word line group has a power supply line shared by a row on a boundary of an adjacent word line group. All power supply lines in a word line group are at a full power voltage in response to one of the rows in the word line group being selected by a word line. Most power supply lines in an adjacent word line group are at a full power voltage. All power supply lines in other word line groups are at a power-gated voltage.

Abstract: A method and circuit for implementing sense amplifiers for sensing local write driver with bootstrap write assist for Static Random Access Memory (SRAM) arrays, and a design structure on which the subject circuit resides are provided. The circuit includes a sense amplifier used in both read and write operations with a write assist boost circuitry. The sense amplifier captures and amplifies write data at a selected SRAM cell column and drives the write data onto local bit lines. The write assist boost circuitry temporarily supplies an increased device voltage differential to the SRAM cell during write operations to significantly increase SRAM cell write ability.

Abstract: An SRAM includes a global bit line, an SRAM cell, precharge logic, discharge logic, and sense logic. The SRAM cell stores a first logical value or a second logic value and is coupled to the global bit line. The precharge logic may charge the global bit line to a precharge voltage for a non-read operation and a boosted voltage that is greater than a reference voltage for a read operation. The discharge logic may either maintain the global bit line at the boosted voltage for the first logical value or discharge the global bit line to a discharge voltage that is less than the reference voltage for the second logical value. The sense logic may output the first logical value when the global bit line has the boosted voltage or may output the second logical value when the global bit line has the discharge voltage.

Abstract: A clock system includes a local clock buffer adapted to receive a variable global clock signal. The local clock buffer produces a first local clock signal from the variable global clock signal. The clock system includes a pulse width logic control circuit in operable communication with the local clock buffer. The pulse width logic control circuit may be adapted to limit the first local clock signal pulse width to be less than the variable global clock signal pulse width during a slow mode. The pulse width logic control circuit may be adapted to expand the first local clock signal pulse width to be greater than the variable global clock signal pulse width during a fast mode. The limited and expanded first local clock signals may signal a local evaluation circuit to address a memory line.

Abstract: An auction methodology wherein the auction competition among the bidders is generated by allowing each bidder to bid for non-price bid parameters (e.g., lead time, labor rate, contract length, etc.) in addition to the price of the lot on auction. Such a multi-parameter bidding provides the buyer (i.e., the auction requester) with more diverse information when selecting the winning bidder. The buyer and each bidder participating in the electronic auction may receive a real-time feedback of the bidding activity including details on bids placed for price and non-price parameters, which allows each bidder to adjust or modify one or more of its own bids (for price and non-price bid parameters) to effectively compete in the auction.

The inverting multiplexer is controlled by the redundancy steering control signal that activates redundancy steering.
