A memory device having a memory controller is configured to operate a hybrid cache including a dynamic cache including XLC blocks and a static cache including the SLC blocks. The memory controller is configured to disable at least one of the static cache or the dynamic cache. A method of operating a memory device includes partitioning a memory array into a first portion of SLC blocks and a second portion of XLC blocks, storing at least a portion of host data into the first portion of SLC blocks as a static cache; and storing at least another portion of the host data into the second portion of XLC blocks in an SLC mode as a dynamic cache responsive to a burst of host data being determined to be greater than the static cache can handle. Additional memory devices, methods, and computer systems are also described.
