    Abstract: A data erase operation is performed on the memory system. The directed data erase operation performed on the memory system erases blocks of the memory device including blocks that are indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as valid without erasing those groups of memory cells (e.g., blocks) indicated as invalid. In some embodiments, a data erase operation that can be performed on a memory system may obtain information associated with failing scenes of groups of memory cells (e.g., blocks) prior to obtaining the information, and erase the blocks (e.g., invalid blocks) subsequently.

    Abstract: A programmable memory device includes a read only memory (ROM) block to store instructions associated with functionality of the programmable memory device. The device includes a memory array having a set of reserved pages to store updates to be performed on the ROM block. The device includes a controller coupled to the ROM block and the memory array. The controller is to execute the instructions to: execute a set features command; program, in execution of the set features command, a set of sub-feature parameters to a specified feature address of the set of reserved pages, wherein the set of sub-feature parameters are to trigger operation within a ROM-emulated memory (REM) profile mode; and program a REM-profiled page of the set of reserved pages with REM data received from a host system.
