DATA READING METHOD, STORAGE CONTROLLER, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/237637
Kind Code:
A1
Abstract:
Disclosed in the present application is a solid state drive data reading method, comprising: a controller receives a read request sent by a host and comprising location indication information of requested data; determine, according to a target physical location indicated by the location indication information, a target read voltage model corresponding to a target storage area where the target physical location is located, each storage area in a non-volatile storage medium comprising multiple target storage units divided according to target division granularity, and a read voltage model being a function related to the identifier of a target storage unit; obtain a parameter value of the target read voltage model from correspondences between storage areas and parameter values of read voltage models; determine a read voltage corresponding to the target physical location according to the identifier of a target storage unit where the target physical location is located, the target read voltage model, and the parameter value of the target read voltage model; obtain the requested data and send same to the host according to the read voltage corresponding to the target physical location.
