Abstract
In some implementations, a controller may select a physical block, of a user data virtual block (VB), for a host write operation or a garbage collection operation. The user physical block previously stored user data. The user physical block has previously been programmed in accordance with triple-level cell (TLC) programming. The controller may determine that an average bit error rate (BER) of the user physical block exceeds an average BER of the VB. The controller may, based on determining that the average BER of the physical block exceeds the average BER of the user VB: swap, for the VB, the user physical block with a system physical block that is allocated for storing system data; swap, for the VB, the user physical block with a reserved physical block; or cause a program time, of the user physical block, to be increased.
