Abstract
Briefly, in accordance with one or more embodiments, a memory array comprises two or more volumes, the volumes comprising two or more dice, respectively. The volumes are connected in a daisy chain configuration such that an output of a first volume is coupled to an input of a next volume, and the dice are connected in a daisy chain configuration such that an output of a first die is coupled to an input of a next die within the volume. In such a configuration, a first die in a first volume is capable of being appointed as part of a second volume.
Claims20
A memory array comprising:
- two or more volumes, the volumes comprising two or more dice, respectively;
- wherein the volumes are connected in a daisy chain configuration such that an output of a first volume is coupled to an input of a next volume;
- and
- wherein the dice are connected in a daisy chain configuration such that an output of a first die is coupled to an input of a next die within the volume.
A method to appoint dice within a memory array, comprising:
- issuing a read status as a first command;
- configuring a volume with Feature 58h before a first FFh;
- configuring one or more logical units within the volume;
- and
- issuing the first FFh.
A solid state drive (SSD), comprising:
- a host interface to couple to a processor via the host interface;
- control logic coupled to the host interface;
- and
- a memory array coupled to the control logic, wherein the memory array comprises:
- two or more volumes, the volumes comprising two or more dice, respectively;
- wherein the volumes are connected in a daisy chain configuration such that an output of a first volume is coupled to an input of a next volume;
- and
- wherein the dice are connected in a daisy chain configuration such that an output of a first die is coupled to an input of a next die within the volume.
An article of manufacture comprising a non-transitory machine-readable medium having instructions stored thereon to appoint dice within a memory array that, if executed, result in:
- issuing a read status as a first command;
- configuring a volume with Feature 58h before a first FFh;
- configuring one or more logical units within the volume;
- and
- issuing the first FFh.
