| 20090070523 | Flash memory device storing data with multi-bit and single-bit forms and programming method thereof - A flash memory device may include a memory cell array including a plurality of memory blocks and a partition information block, the partition information block storing partition information that indicates a boundary between multi-bit memory blocks and single-bit memory blocks among the memory blocks. The memory device may include a control logic configured to determining whether a memory block that a block address from the outside indicates has a multi-bit form or a single-bit form based on the partition information and to control program and read operations in a multi-bit form or a single-bit form based on a determination result. The control logic automatically programs data in the partition information block according to whether a fuse connected to the control logic fuse is cut or not, the data being used for preventing the partition information block from being programmed or erased. | 03-12-2009 |

| 20080310226 | Multi-Bit Flash Memory Devices Having a Single Latch Structure and Related Programming Methods, Systems and Memory Cards - Multi-bit flash memory devices are provided. The multi-bit flash memory device includes an array of memory cells and a page buffer block including page buffers. Each of the page buffers has a single latch structure and performs a write operation with respect to memory cells according to loaded data. 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. | 12-18-2008 |
