摘要： A flash memory device includes multiple memory blocks, a decoder configured to select at least one of the memory blocks in response to block select signals, a controller configured to generate the block select signals in response to a block address and to generate a flag signal when the block address corresponds to a bad block, and an output buffer configured to output fixed data in response to the flag signal indicating that the block address corresponds to the bad block. When the block address corresponds to a bad block, the controller generates the block select signals to cause the decoder to interrupt selection of a memory block corresponding to the block address.

摘要： A voltage boosting circuit for an integrated circuit includes a booster and a voltage clamp circuit. The booster generates a boosted voltage higher than the supply voltage in response to a boosting control signal. The voltage clamp circuit includes a voltage detector, a pulse generator, and a discharge circuit. The voltage detector generates, in response to the boosting control signal, a detected voltage signal representing an attribute of the boosted voltage. The pulse generator generates a pulse signal responsive to the detected voltage signal. And the discharge circuit discharges the boosted voltage during an activation period of the pulse signal. This largely stabilizes the output voltage of the booster.

摘要： A flash memory and a program method of the flash memory include applying a pass voltage to word lines to boost a channel voltage, which is discharged to a ground voltage. A program voltage is applied to a selected word line and a local voltage is applied to at least one word line supplied with the pass voltage while the program voltage is being applied to the selected word line. The local voltage is lower than the pass voltage and equal to or higher than the ground voltage. The boosted channel voltage may be discharged before the program voltage is applied to the selected word line.
