Abstract:
PURPOSE: A nonvolatile memory device is provided to minimize current consumption by enabling the number or location of required internal voltage drivers at each operation section. CONSTITUTION: A scheduler(110) successively provides sector information in a busy state. An enabler(120) provides a selection signal according to the section information. An internal voltage generating unit(130) includes a plurality of internal voltage drivers. The internal voltage driver selected according to the selection signal is enabled.
Abstract:
PURPOSE: A non-volatile semiconductor device is provided to reduce a bit lien bias time by including a bit line bias block and biasing the bit line together with a page buffer. CONSTITUTION: A memory cell array(100) comprises a plurality of memory blocks and one or more bit line bias block. A page buffer precharges a plurality of bit lines. The page buffer(150) detects data stored in at least memory block through the plural bit lines. A controller controls the operation of a non-volatile memory device. The controller controls the bit line bias block and the page buffer to precharge the plural bit lines.

결함 칼럼 발생에 관계없이 메모리 셀 어레이에 저장된 초기 셋팅 데이터를 정상적으로 독출할 수 있는 불휘발성 메모리 장치 및 그 구동방법이 개시된다. 상기 불휘발성 메모리 장치의 구동방법에 따르면, 동작 환경 설정에 관련된 설정정보가 메모리 셀 어레이에 할당된 복수의 영역 각각에 복사되어 저장되는 메모리 장치로 전원을 제공하는 단계와, 상기 메모리 셀 어레이에 대한 초기 독출동작을 수행하는 단계와, 복수 개로 저장된 상기 설정정보의 독출결과에 기반하여 초기 셋팅 데이터를 결정하는 단계 및 상기 결정된 초기 셋팅 데이터를 이용하여 메모리 장치의 동작 환경을 설정하는 단계를 구비하는 것을 특징으로 한다.
Abstract:
A flash memory device including a row decoder having no bad block data storage means and control method thereof is provided to realize a high reliable flash memory without a fuse or latch circuit at a row decoder. In a flash memory device, a decoder(140), not having a storing unit for bad block information, selects at least one of a plurality of memory blocks. A controller(110) generates a block selection signal in response to a block address. When the block address is bad, the controller generates a block selection signal for preventing a decoder from selecting the memory block.
