  • System and method of reading data from memory concurrently with sending write data to the memory
    Patent number: 9741442
    Abstract: A data storage device includes a memory, a controller, and a communication bus coupled to the memory and to the controller. The controller is configured to send a read-write command and write data to the memory via the communication bus. The read-write command indicates an address of requested data to be read from the memory. The controller is further configured to receive the requested data read from the memory. Communicating the requested data over the communication bus overlaps the write data being stored into the memory.
    Type: Grant

  • Data modification based on matching bit patterns
    Patent number: 9128827
    Abstract: A data storage device includes a memory and a controller. The controller is configured to identify groups of bits that match any bit pattern in a first set of bit patterns. Each of the groups of bits includes a first bit of first data, a second bit of second data, and a third bit of third data to be stored at the memory. The controller is configured, based on determining that a count of the identified groups exceeds a threshold, to change multiple bits of the first data. Changing the multiple bits of the first data reduces a number of the groups of bits that match any bit pattern in the first set of bit patterns.

Each of the groups of bits includes a first bit of first data, a second bit of second data, and a third bit of third data to be stored at the memory. The controller is configured, in response to determining that a count of the identified groups exceeds a threshold, to change multiple bits of the first data. Changing the multiple bits of the first data reduces a number of the groups of bits that match any bit pattern in the first set of bit patterns.
