Method and apparatus for data protection in memory devices
An apparatus and method for efficiently transmitting data are described. A transmitter sends data to a receiver. An encoder of the transmitter divides a received first block of data into multiple sub-blocks. The encoder selects a portion of each sub-block to compare to one another. A portion in a particular sub-block has a same offset and a same size as other portions of other sub-blocks. If the encoder determines the multiple portions match one another, the encoder sends, to the receiver, a second block of data corresponding to the first block of data. The second block of data has a same size as a size of the received first block of data, and the second block of data includes security data from one of multiple error correction schemes. Therefore, the second block of data provides security without increasing an amount of data to transmit.
