Abstract: A method of operating a controller which controls a nonvolatile memory device includes enabling a command latch enable signal, an address latch enable signal, and a write enable signal and transmitting multiple data signals including a command and an address to the nonvolatile memory device in synchronization with the enabled write enable signal. A number of DQ lines through which the plurality of data signals are transmitted is greater than a number of bits of each of the data signals. The method also include disabling the command latch enable signal after the command is transmitted, and disabling the address latch enable signal and the write enable signal after the address is transmitted.

Abstract: A storage device includes a controller and a memory. In response to a request of a host, the controller generates: (A) a first list as a result of counting: (1) the number of first page numbers included in a first range among page numbers included in a logical address received from the host and (2) the number of second page numbers included in a second range not overlapping the first range, (B) generates a second list as a result of respectively grouping the first page numbers and the second page numbers based on the first list, and (C) translates the logical address to a physical address based on the second list and the first map data. The memory stores the first map data to be provided to the controller. The first map data matches the first page numbers and the second page numbers with respective physical addresses.

Abstract: A memory controller is used to control a first storage block having a first data rate and a second storage block having a second data rate. The memory controller includes; a memory interface that transceives a data signal and a data strobe signal with the first and second storage blocks, and a sub controller that stores access information about the first data rate and the second data rate. The sub controller may include a delay lookup table storing access information including first strobe adjustment timing information defining a first data strobe signal provided to the first storage block, and second strobe adjustment timing information defining a second data strobe signal provided to the second storage block.

Abstract: A non-volatile memory and a method of controlling an erase operation of the non-volatile memory using a controller are provided. The method of controlling the erase operation includes beginning performance of the erase operation, monitoring a next command to be performed in the non-volatile memory while performing the erase operation, determining an erase status, and continuing, suspending or canceling the erase operation based on the determination result of the erase status.
