Abstract
A storage device includes a memory including a first file storage area where a first file is stored and a controller. Such a controller may perform one or more first read operations using a first read voltage on a first portion of the first file storage area. The controller may, when a specific one of the first read operations fails, search for a second read voltage and perform one or more second read operations using the second read voltage on a second portion of the first file storage area other than the first portion.
Claims20
A storage device comprising:
- a memory including a first file storage area where a first file is stored;
- and
- a controller configured to perform one or more first read operations using a first read voltage on a first portion of the first file storage area and configured to, when a specific one of the first read operations fails, search for a second read voltage and perform one or more second read operations using the second read voltage on a second portion of the first file storage area other than the first portion.
A memory device comprising:
- a first file storage area including a plurality of first word lines and storing a first file therein;
- and
- a second file storage area including a plurality of second word lines and storing a second file therein,
- wherein, according to a first read command for the first file, one or more first read operations using a first read voltage are performed on a first group of the plurality of first word lines, and one or more second read operations using a second read voltage is performed on a second group of the plurality of first word lines.
1 more element
A controller comprising:
- a command receiving circuit configured to receive a read command and information on a file according to the read command;
- and
- a read operation control circuit configured to control one or more first read operations using a first read voltage on a first portion of a first file storage area storing the file, and configured to, when a specific one of the first read operations fails, search for a second read voltage and control one or more second read operations using the second read voltage on a second portion of the first file storage area other than the first portion.
