Abstract
A programmable memory device includes a ROM block to store instructions associated with functionality of the programmable memory device, a memory array having reserved pages to store updates to be performed on the ROM block, and a controller coupled to the ROM block and the memory array. The controller is to, in response to receipt of a remote command from a vendor server via a host system, execute the instructions to perform operations including: executing a set features command to access the set of reserved pages, as an extension to one time programmable mode; programming a set of sub-feature parameters to a specified feature address of the reserved pages, where the set of sub-feature parameters are to trigger operation within a ROM-emulated memory (REM) profile mode; and programming a REM-profiled page of the reserved pages with REM data received from the vendor server via the host system.
