Abstract
A memory system includes a nonvolatile memory and a controller. The controller is configured to determine a first predicted read address as a subsequent read address following an input read address from which data is to be read, based on the input read address and a preset write sequence rule, determine a second predicted read address as the subsequent read address, based on the input read address and a read sequence history, select one of read addresses including the first and second predicted read addresses as a target read address, and read data from the target read address of the nonvolatile memory.

A memory system comprising:
- a nonvolatile memory;
- and
- a controller configured to:
- determine a first predicted read address as a subsequent read address following an input read address from which data is to be read, based on the input read address and a preset write sequence rule;
- determine a second predicted read address as the subsequent read address, based on the input read address and a read sequence history;
- select one of read addresses including the first and second predicted read addresses as a target read address;
- and
- read data from the target read address of the nonvolatile memory.
A method for reading data from a nonvolatile memory, comprising:
- determining a first predicted read address as a subsequent read address following an input read address from which data is to be read, based on the input read address and a preset write sequence rule;
- determining a second predicted read address as the subsequent read address, based on the input read address and a read sequence history;
- selecting one of read addresses including the first and second predicted read addresses as a target read address;
- and
- reading data from the target read address of the nonvolatile memory.
