Memory devices and electronic systems having a hybrid cache including static and dynamic caches, and related methods

A memory device, comprising:

• a memory array including:
• a first set of memory blocks of non-volatile memory cells;
• and
• a second set of memory blocks of non-volatile memory cells;
• and
• a memory controller configured to:
• write host data to the first set of memory blocks including static cache of a hybrid cache of the memory array;
• write the host data to the second set of memory blocks including dynamic cache of the hybrid cache if the static cache is unavailable;
• and
• disable the static cache responsive to comparing program/erase (PE) cycles consumed by the static cache against a maximum threshold for the static cache;
• and
• disable the dynamic cache responsive to comparing PE cycles consumed by the dynamic cache against a maximum threshold for the dynamic cache.
