Abstract
A controller includes a host interface and a processor. The host interface is configured for communicating with a host. The processor is configured to receive from the host, via the host interface, instructions for execution in a Non-Volatile Memory (NVM), to identify among the instructions an instruction, which pertains to a secure monotonic counter and is intended for execution in an NVM having a secure monotonic counter embedded therein, and to execute the identified instruction, and respond to the host responsively to the instruction, instead of the NVM.
