Abstract: Semiconductor devices may include an active pattern, a gate structure in an upper portion of the active pattern, a bit line structure on the active pattern, a lower spacer structure on a lower portion of a sidewall of the bit line structure, and an upper spacer structure on an upper portion of the sidewall of the bit line structure. The lower spacer structure includes first and second lower spacers sequentially stacked, the first lower spacer contacts the lower portion of the sidewall of the bit line structure and does not include nitrogen, and the second lower spacer includes a material different from the first lower spacer. A portion of the upper spacer structure contacting the upper portion of the sidewall of the bit line structure includes a material different from the first lower spacer.

Abstract: A flash memory based storage system and operating method are provided. A host of the storage system requests an erase unit size from the storage device and uses a multiple of the erase unit size to partition a logical address. Each host block may be assigned a state selected from a group of states including: an open state in which an erase unit of the storage device is allocated, a write state in which data is written at an erase unit of the storage device, a close state in which a write operation is no longer performed, and an invalidate state in which valid data of a host block is invalidated.
