Abstract: Semiconductor device capable of preventing off-leakage of the transistor may include a pulse voltage generator configured to generate a pulse voltage, and a transistor configured to have a gate provided with the pulse voltage. The transistor is in an off state in response to the pulse voltage.

Abstract: An SRAM circuitry having SRAM cells for storing at least one data word of a length of at least one bit is provided. Each bit of the data words is stored in an assigned SRAM cell, wherein the SRAM circuitry comprises address lines for addressing the at least one data word, a decoding unit for decoding the address signals on the address lines to generate a word line signals on a word line per addressed word, a local bit line to be coupled to SRAM cells of different data words with different addresses, a global bit line to be coupled to the local bit line, and a global bit line restore unit for pre-charging the global bit line. The global bit line restore unit is configured for being triggered by a trigger signal based on the address signal of one of the decoded address lines.

Abstract: The programming method of the present invention minimizes program disturb by initially programming cells on the same wordline with the logical state having the highest threshold voltage. The remaining cells on the wordline are programmed to their respective logical states in order of decreasing threshold voltage levels.
