Abstract
A disclosed example to use an erase-suspend feature on a memory device includes a host interface to receive a first erase command to perform an erase operation; and a control circuit to: based on the erase-suspend feature being enabled at the memory device, suspend the erase operation based on determining that a length of time equal to an erase segment duration value has elapsed, the length of time elapsed being relative to a start of an erase segment, and the erase segment duration value specified in a configuration parameter for the erase-suspend feature; perform a second memory operation when the erase operation is suspended; and after the second memory operation is complete, resume the erase operation based on receiving a second erase command from the memory host controller.
