摘要： A memory device includes a memory array including a number of memory cell strings, a number of bit lines, a number of pre-charge circuits coupled to the memory cell strings, and a number of sense amplifier circuits coupled to the memory cell strings through the bit lines. Each memory cell string includes at least one first select transistor, a second select transistor and at least one memory cell. Each bit line includes a third select transistor, and is coupled to a memory cell string. During a pre-charging stage, the pre-charge circuits provide a first voltage to pre-charge the memory cell strings. During a programming stage, for the memory cell strings to be inhibited, the sense amplifier circuits provide a second voltage lower than the first voltage. For the memory cell strings to be programmed, the sense amplifier circuits provide a third voltage lower than the second voltage.

摘要： A method and a circuit for generating a clock signal from a clock integrated circuit are introduced herein. A compensation voltage is generated according to a temperature coefficient of a resistor and a clock period of a clock circuit, where the compensation voltage is resistor-corner independent. The clock period of the clock circuit is determined by the resistor and at least one capacitor of the clock circuit. The temperature dependence of the clock period of the clock circuit is reduced according to the compensation voltage.
