receive at least one fourth command to designate the at least one of the plurality of predefined access types associated with the memory device.
10. The memory device of claim 1 , wherein the at least the portion of the memory comprises a partition of the memory.
11. The memory device of claim 1 , wherein the controller is further configured to:
receive at least one fourth command to configure access to the memory device in accordance with a second one of the plurality of predefined access types such that at least a second portion of the memory is configured according to the second one of the plurality of predefined access types for at least one usage; and
receive at least one fifth command to activate the second one of the plurality of predefined access types associated with the memory device.
12. The memory device of claim 1 , further comprising one or more registers storing at least one of: (i) an indication of the plurality of predefined access types, (ii) the at least one of the plurality of predefined access types, or (iii) an at least one currently active predefined access type.
13. A method comprising:
receiving, by a controller of a memory device and from a host device at a first time, at least one first command to configure access to the memory device in accordance with at least one of a plurality of predefined access types;
configuring, based at least in part on the at least one first command, at least a portion of a memory of the memory device according to the at least one of the plurality of predefined access types for at least one usage;
receiving, at a second time after the first time, at least one second command to activate the at least one of the plurality of predefined access types associated with the memory device;
activating, based at least in part on the at least one second command, the at least one of the plurality of predefined access types associated with the memory device;
receiving, after the at least one second command, at least one third command to write data to the portion of the memory device according to the activated at least one of the plurality of predefined access types; and
writing, based at least in part on the at least one third command, data to the portion of the memory according to the activated at least one of the plurality of predefined access types.
14. The method of claim 13 , wherein the memory comprises NAND memory and the at least the portion of the memory comprises a block of the NAND memory.
