Abstract:
A semiconductor memory device includes a NAND memory including a plurality of blocks, each of which is a unit of data erasing, and a controller. The controller is configured to select an initial value from a group of initial values, based on an address of the NAND memory in which data are to be written, set a value corresponding to the selected initial value to a linear feedback shift register circuit, randomize the data using an output value of the linear feedback shift register circuit, and write the randomized data to the address of the NAND memory. A size of each of the blocks S is smaller than 2 n-1  bytes, n being a number of registers included in the linear feedback shift register circuit.

Claim (Index 11):
A semiconductor memory device, comprising:\n a non-volatile memory; and a memory controller including a randomizer circuit configured to randomize write data that is received along with a write command, and write the randomized write data to an address of the non-volatile memory that is also received along with the write command, wherein the randomizer circuit includes a linear feedback shift register circuit and a controller circuit, and the controller circuit is configured to: shift an index associated with the address of the non-volatile memory, select an initial value associated with the shifted index from a group of initial values, by referring to correspondence between the initial values and indices, each of which is associated with at least an address of the non-volatile memory, set a value corresponding to the selected initial value in the linear feedback shift register circuit, and randomize the write data using one or more output values output from the linear feedback shift register circuit.
