Abstract
Memory devices, connectors and methods for terminating an operation are provided, including a memory device configured to terminate an internal operation such as a programming or erase operation responsive to receiving a signal during removal of the memory device from a connector, such as a socket. The memory device may be specially configured to generate the removal signal, such as by including a dedicated removal terminal. The memory card may respond to the signal by terminating a programming or erase operation before power is lost. The removal terminal may have a dimension that is different from a dimension of a power terminal through which the memory device receives power. Alternatively, the connector may be specially configured to generate a signal that causes a host to terminate programming or erase operations in the memory device prior to memory card removal, such as by including a switch that is actuated when the memory device moves to a pre-power loss position.
