1. A system comprising:
a dynamic random access memory (DRAM) configured to store data for a host device, the DRAM comprising a plurality of regions;
a plurality of signature generators, each signature generator associated with a respective region of the DRAM;
and
a controller configured to:
receive, from the host device, a command;
in response to receiving the command, read data from a first region of the DRAM;
generate, using a first signature generator and based on the data read from the first region, a first signature;
store the first signature; and
in response to generating the first signature, update a register to indicate that the first signature has been generated, wherein updating the register comprises updating from a first value to a second value.
