APPOINTING SEMICONDUCTOR DICE TO ENABLE HIGH STACKING CAPABILITY
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.
1 . 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.
2 . A memory array as claimed in claim 1 , wherein the volumes are disposed in a stacked configuration.
3 . A memory device as claimed in claim 1 , wherein the daisy chain configuration of the dice is part of the daisy chain configuration of the volumes such that an input of a volume is coupled to an input of a first die within the volume and an output of a last die of the volume is coupled to an output of the volume.
4 . A memory array as claimed in claim 1 , wherein a first die in a first volume is capable of being appointed as part of a second volume.
5 . A memory array as claimed in claim 1 , wherein the dice may be powered up in a staggered order a logical unit level.
6 . 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.
7 . A method as claimed in claim 6 , wherein the first FFh issued will accepted only from an appointed logical unit within the configured volume.
8 . A method as claimed in claim 6 , further comprising appointing a first die in another volume as part of the configured volume.
9 . A method as claimed in claim 6 , further comprising powering one or more dice in a staggered order in the volume or in another volume, or a combination thereof, at a logical unit level.
10 . A method as claimed in claim 6 , wherein one or more dice within the configured volume and one or more device within another volume may be initialized in any selected order.
11 . 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.
12 . A solid state drive as claimed in claim 11 , wherein the volumes are disposed in a stacked configuration.
13 . A solid state drive as claimed in claim 11 , wherein the daisy chain configuration of the dice is part of the daisy chain configuration of the volumes such that an input of a volume is coupled to an input of a first die within the volume and an output of a last die of the volume is coupled to an output of the volume.
14 . A solid state drive as claimed in claim 11 , wherein a first die in a first volume is capable of being appointed as part of a second volume.
15 . A solid state drive as claimed in claim 11 , wherein the dice may be powered up in a staggered order a logical unit level.
16 . 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.
17 . An article of manufacture as claimed in claim 6 , wherein the first FFh issued will accepted only from an appointed logical unit within the configured volume.
18 . An article of manufacture as claimed in claim 6 , wherein the instructions, if executed, further result in appointing a first die in another volume as part of the configured volume.
19 . An article of manufacture as claimed in claim 6 , wherein the instructions, if executed, further result in powering one or more dice in a staggered order in the volume or in another volume, or a combination thereof, at a logical unit level.
20 . An article of manufacture as claimed in claim 6 , wherein one or more dice within the configured volume and one or more device within another volume may be initialized in any selected order
