Abstract

Method and apparatus that relate to a storage device comprising a plurality of memory cells, an interface device configured to connect the storage device to a host system and configured to transmit signals to read and write data from the host system to the memory cells via a first and second data path, and a logic unit. The logic unit is configured to read and write data from the plurality of memory cells via the second data path, and configured to perform logic operations on data stored in the plurality of memory cells. When performing read and write operations, the first data path excludes the logic unit, and the second data path includes the logic unit. Furthermore, the logic unit is communicatively coupled between the interface device and the plurality of memory cells. Additionally, a method for manufacturing the memory device is provided.
