    摘要: A memory device includes a plurality of memory blocks. Each memory block includes a plurality of bit lines, a plurality of word lines, a plurality of memory cells provided at intersections of the bit lines and word lines; a plurality of capacitors, and a plurality of sense amplifiers. Each sense amplifier has a first input and a second input. The first input is connected to a first bit line of a first one of the memory blocks and is coupled via one of the capacitors to a first bit line of a second one of the memory blocks. The second input of the input is connected to a second bit line of the second one of the memory blocks and is coupled via one of the capacitors to a second bit line of the first one of the memory blocks.

    摘要: A semiconductor memory device having a column redundancy scheme for improving redundancy efficiency includes sub memory blocks, a redundancy memory block, global data input output lines respectively associated with the sub memory blocks, a redundancy global data input output line and switches. Each of the sub memory blocks has a plurality of memory cells. The redundancy memory block has a plurality of redundancy memory cells. The data of selected memory cells of a sub memory block are transmitted to a corresponding global data input output line. The data of selected redundancy memory cells of the redundancy memory block are transmitted to the redundancy global data input output line. A switch switches the global data input output line to the redundancy global data input output line if a memory cell connected to the global data input output line is defective.

    摘要: The memory device includes a memory array, control logic and a recovery circuit. The memory array has a first region configured to store data, a second region configured to store a portion of fail cell information, and a third region configured to store recovery information. The fail cell information identifies failed cells in the first region, and the recovery information is for recovering data stored in the identified failed cells. The control logic is configured to store the fail cell information, to transfer the portion of the fail cell information to the second region of the memory array, and to determine whether to perform a recovery operation based on address information in an access request and the portion of the fail cell information stored in the second region. The access request is a request to access the first region. The recovery circuit is configured to perform the recovery operation.
