摘要： In a read method for a memory device, a bit line is set with data in a first memory cell; and the data on the bit line is stored in a register. The data in the register is transferred to a data bus while setting the bit line with data in a second memory cell. In another read method for a memory device, a bit line of a first memory cell is initialized and the bit line is pre-charged with a pre-charge voltage. Data in a memory cell on the bit line is developed, and a register corresponding to the bit line is initialized. The data on the bit line is stored in the register. The data in the register is output externally while performing the initializing, pre-charging, making and initializing to set the bit line with data in a second memory cell.

A buffer random access memory (RAM) is configured to store program data provided from an external host device during a multi-bit program operation. Control logic is provided that is configured to control the page buffer block and the buffer RAM so that program data stored in the buffer RAM is reloaded into the page buffer block whenever data programmed before the multi-bit program operation is compared with data to be currently programmed. The control logic is configured to store data to be programmed next in the buffer RAM before the multi-bit program operation is completed.

摘要： Methods of performing multi-block erasing operations on a memory device that includes a plurality of memory blocks are provided. Pursuant to these methods, the rate at which a first voltage that is applied to the memory blocks that are to be erased during the multi-block erasing operation rises is controlled based on the number of memory blocks that are to be erased. The memory device may be a flash memory device, and the first voltage may be an erasing voltage that is applied to a substrate of the flash memory device. The rate at which the first voltage rises may be set so that the substrate of the flash memory device reaches the erasing voltage level at approximately the same time regardless of the number of memory blocks that are to be erased.
