Abstract: A memory device, and a method of operating the same, includes a plurality of memory cells configured to be programmed to any one of a plurality of program states, a peripheral circuit configured to perform a plurality of program loops on the plurality of memory cells, and a program operation controller. The program operation controller is configured to control the peripheral circuit such that a verify operation for a second program state is performed from a second program loop after a verify operation for a first program state performed from a first program loop passes, wherein the first program loop is performed before the second program loop.

Abstract: Provided herein is a memory device for performing a program operation, a method of operating the memory device, and a storage device having the memory device. The method of operating a memory device includes receiving a first data bit among a plurality of data bits to be stored in each of a plurality of memory cells from a memory controller, performing a program voltage apply operation on the plurality of memory cells based on the first data bit, and receiving a second data bit among the plurality of data bits from the memory controller while performing the program voltage apply operation.

Abstract: Provided is a cutting biopsy instrument facilitating loading by minimizing a change in a grip on a biopsy instrument and enhancing tissue sampling accuracy and safety and simplifying collection of sampled tissue by proposing a new shift relation between an stylet and an cannula at the shooting of the needles.
