ABSTRACT:
Multi-bit programming apparatuses and/or methods are provided. A multi-bit programming apparatus may comprise: a multi-bit cell array that includes a first multi-bit cell and a second multi-bit cell; a programming unit for programming first data in the first multi-bit cell, and programming second data in the second multi-bit cell; and a verification unit for verifying whether the first data is programmed in the first multi-bit cell using a first verification voltage, and verifying whether the second data is programmed in the second multi-bit cell using a second verification voltage. The multi-bit programming apparatus may generate better threshold voltage distributions in a multi-bit cell memory.
