In an example, a portion of a memory array may be selected to be wear leveled based on how often the portion is or is to be accessed. The portion may be wear leveled.
1. A method of operating an apparatus, comprising:
selecting a portion of a memory array to be wear leveled based on how often the portion is or is to be accessed; and
wear leveling the portion;
wherein selecting the portion to be wear leveled comprises a host setting a first register that corresponds to the portion to allow the portion to be wear leveled and setting a number of second registers that correspond to remaining portions of the memory array to not allow the remaining portions to be wear leveled.
2. The method of claim 1 , comprising setting the first register and setting the number of second registers in response to a command from the host.
3. The method of claim 1 , wherein setting the first register is in response to the host determining that the portion was accessed greater than or equal to a certain number of times, and wherein setting the number of second registers to not allow the remaining portions to be wear leveled is in response to the host determining that the remaining portions were accessed less than the certain number of times.
4. The method of claim 1 , wherein selecting the portion to be wear leveled comprises selecting a portion of a ferroelectric memory array to be wear leveled.
5. An apparatus, comprising:
a host; and
a memory coupled to the host and comprising an array of memory cells; wherein:
the memory is configured to select a portion of a memory array to be wear leveled based on how often the portion is or is to be accessed; and
the host is configured to set a first register of the memory that corresponds to the portion to allow the portion to be wear leveled and to set a number of second registers that correspond to remaining portions of the memory array to not allow the remaining portions to be wear leveled.
6. The apparatus of claim 5 , wherein the host is configured to send a command that causes the memory to set the first register to allow the portion to be wear leveled and to set the number of second registers to not allow the remaining portions to be wear leveled.
7. The apparatus of claim 5 , wherein the host is configured to set the first register in response to the host determining that the portion was accessed greater than or equal to a certain number of times, and wherein host is configured to set the number of second registers to not allow the remaining portions to be wear leveled in response to the host determining that the remaining portions were accessed less than the certain number of times.
8. The apparatus of claim 5 , wherein the memory array is a ferroelectric memory array.
