Abstract
A non-volatile memory operated through multiple channels. The non-volatile memory includes a plurality of chip-enable-signal controlled areas, each containing a plurality of dies. Simultaneous operations on the different dies of at least one target chip-enable-signal controlled space corresponding to a target channel are allowed. The control unit scans the non-volatile memory to check the health status of the dies of the target chip-enable-signal controlled space to assign a plurality of logical enable signals of the target channel to correspond to the dies of the target chip-enable-signal controlled space.
Claims20
A data storage device, comprising:
- a non-volatile memory, including a plurality of chip-enable-signal controlled areas, wherein each chip-enable-signal controlled area includes a plurality of dies;
- and
- a control unit, operating the non-volatile memory through multiple channels for simultaneously operating different dies of at least one target chip-enable-signal controlled area corresponding to a target channel,
- wherein:
- the control unit scans the non-volatile memory to check the health status of the dies of the at least one target chip-enable-signal controlled area to assign a plurality of logical enable signals of the target channel to correspond to the dies of the at least one target chip-enable-signal controlled area.
A method for operating a data storage device, comprising:
- operating a non-volatile memory of the data storage device through multiple channels for simultaneously operating different dies of at least one target chip-enable-signal controlled area corresponding to a target channel, wherein the non-volatile memory includes a plurality of chip-enable-signal controlled areas, and each chip-enable-signal controlled area includes a plurality of dies;
- and
- scanning the non-volatile memory to check the health status of the dies of the at least one target chip-enable-signal controlled area to assign a plurality of logical enable signals of the target channel to correspond to the dies of the at least one target chip-enable-signal controlled area.
