Abstract
In one embodiment, an apparatus comprises a memory array and a controller. The controller is to receive a first read command specifying a read voltage offset profile identifier; identify a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset; and perform a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.
Claims20
An apparatus comprising:
- a memory array;
- and
- a controller to:
- receive a first read command specifying a read voltage offset profile identifier;
- identify a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset, wherein a read voltage offset of the at least one read voltage offset is specified as an amount to shift a corresponding read voltage, wherein the corresponding read voltage is to be applied during a read operation specified by a second read command that specifies a same type of read as the first read command;
- and
- perform a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.
A method comprising:
- receiving a first read command specifying a read voltage offset profile identifier;
- identifying a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset, wherein a read voltage offset of the at least one read voltage offset is specified as an amount to shift a corresponding read voltage, wherein the corresponding read voltage is to be applied during a read operation specified by a second read command that specifies a same type of read as the first read command;
- and
- performing a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.
A system comprising:
- a storage device comprising:
- a memory device comprising a memory array and a first controller;
- and
- a second controller to:
- send a configuration command to the first controller, the configuration command specifying at least one read offset voltage and a read voltage offset profile identifier;
- and
- send a read command to the first controller, the read command specifying the read voltage offset profile identifier and an address of the memory array.
