Redundant array management techniques

A memory system, comprising:

• a non-volatile memory device;
• a volatile memory device coupled with the non-volatile memory device and configured to store information associated with operating the non-volatile memory device;
• a first redundant array controller coupled with the volatile memory device and configured to generate first parity data to correct errors associated with a first type of failure that is associated with accessing data in the non-volatile memory device, the first parity data associated with a redundant array of independent nodes;
• and
• a second redundant array controller coupled with the volatile memory device and configured to generate second parity data to correct errors associated with a second type of failure that is associated with accessing data in the non-volatile memory device, the second parity data associated with the redundant array of independent nodes, wherein the second redundant array controller is further configured to store the second parity data in the volatile memory device until a threshold quantity of pages in a block that stores second data stores valid data.

A non-transitory computer-readable medium storing code comprising instructions which, when executed by a processor of a memory system, cause the memory system to:

• receive a first write command associated with writing first data to a first type of memory cell;
• generate, using a first redundant array controller of a redundant array of independent nodes associated with a non-volatile memory device, first parity data corresponding to the first data, the first parity data associated with the redundant array of independent nodes;
• receive a second write command associated with writing second data to a second type of memory cell different than the first type of memory cell;
• generate, using a second redundant array controller of the redundant array of independent nodes different than the first redundant array controller, second parity data corresponding to the second data, the second parity data associated with the redundant array of independent nodes;
• and
• store the second parity data in a volatile memory device coupled with the first redundant array controller and the second redundant array controller.
