    Abstract: 【課題】薄膜BOX−SOI構造のSRAMを内蔵した半導体装置において、データを保持して動作状態とスタンバイ状態とを切り替える。 【解決手段】閾値電圧が低い状態の動作モード(Active mode)と、閾値電圧が高い状態のスタンバイモード(Standby mode)との間に中間モードを設定し、動作モードからスタンバイモードへ移行する際は、動作モードの閾値電圧から、一旦中間モードの閾値電圧に上げて、その後、中間モードの閾値電圧からスタンバイモードの閾値電圧に上げる。また、スタンバイモードから動作モードへ移行する際は、スタンバイモードの閾値電圧から、一旦中間モードの閾値電圧に下げて、その後、中間モードの閾値電圧から動作モードの閾値電圧に下げる。 【選択図】図5

    Abstract translation: 要解决的问题:提供一种包括具有薄膜BOX-SOI结构的内置SRAM的半导体器件,其能够在保持数据的同时在活动状态和待机状态之间切换。解决方案:将中间模式设置在 阈值电压低的活动模式和阈值电压高的待机模式。 在从活动模式转换到待机模式时,临时电压从活动模式中的阈值电压增加到中间模式中的阈值电压,然后从中间模式的阈值电压增加到待机模式。 在从待机模式转换到主动模式时,阈值电压从待机模式中的阈值电压暂时降低到中间模式中的阈值电压,然后从中间模式的阈值电压降低到活动模式中的阈值电压。

    Abstract: PROBLEM TO BE SOLVED: To provide an improved multiport SRAM.SOLUTION: In a multiple port SRAM 10, a first bit cell 38 is coupled to a first word line WL0A and a second word line WL0B and a first bit line pair BL0A/BL0Ab and a second bit line pair BL0B/BL0Bb. A first data line pair DLA, DLAb is coupled to the first bit line pair via first switching logic 52, 54. A second data line pair DLB, DLBb is coupled to the first bit line pair via second switching logic 56, 58 and to the second bit line pair via third switching logic 60, 62. If a row address match but not a column address match exists between a first access address and a second access address, the second switching logic selectively connects the second data line pair with the first bit line pair based on a first decoded signal generated from the column address of the second access address, and the third switching logic decouples the second data line pair from the second bit line pair.

    Abstract: PROBLEM TO BE SOLVED: To suppress data corruption of a memory cell.SOLUTION: Bit line potential detection circuits BD00, BD01 are respectively connected to bit line pairs B00, xB00, B01, xB01. Bit line potential detection circuits BD10, BD11 are respectively connected to bit line pairs B10, xB10, B11, xB11. The bit line potential detection circuits BD00 to BD11 detect potential differences of the bit line pairs B00, xB00 to B00, xB11, and output detection signals DS00 to DS11 of levels corresponding to detection results. A word line voltage adjustment circuit 31 outputs a level adjustment signal WLC on the basis of detection signals DS00 to DS11 of the bit line potential detection circuits BD00 to BD11. A word line driver 21 connected to a selected word line WL0 supplies a high potential power supply voltage or a voltage lower than the high potential power supply voltage by a predetermined value to the word line WL0 in accordance with the level adjustment signal WLC.
