Methods of operating a memory device

A method of operating a memory device, comprising:

• comparing an input address to one or more addresses stored in the memory device, wherein each address of the one or more addresses comprises a corresponding indicator having a status value, and wherein each address of the one or more addresses is stored in at least one memory array selected from a group consisting of a first memory array of the memory device and a second memory array of the memory device;
• if the input address matches a stored address, determining a status value of an indicator corresponding to the matched address;
• if the indicator has a first status value, storing data corresponding to the input address to a third memory array of the memory device and to a fourth memory array of the memory device;
• if the indicator has a second status value, and the stored address is stored in the first memory array, storing the data corresponding to the input address to the third memory array;
• and
• if the indicator has the second status value, and the stored address is stored in the second memory array, storing the data corresponding to the input address to the fourth memory array.

A method of operating a memory device, comprising:

• comparing an input address to one or more addresses stored in the memory device and indicative of problematic memory cells of the memory device;
• if the input address matches a stored address, determining whether a status value of an indicator corresponding to the matched address has a first status value indicative of the matched address corresponding to an address of a dynamic data cache of the memory device or a second status value indicative of the matched address corresponding to an address of a memory array of the memory device, wherein the memory array comprises a first memory array and a second memory array in communication with the dynamic data cache;
• and
• if the indicator has the first status value, storing data corresponding to the input address in the first memory array and storing the data corresponding to the input address in the second memory array;
• and
• if the indicator has the second status value, storing the data corresponding to the input address in either the first memory array or the second memory array.
