Abstract: An apparatus for use with a memory device that has a plurality of memory-device terminals having respective unique bit significances is described. The apparatus includes a memory controller, which includes (i) a plurality of external terminals, each one of the external terminals configured to be in communication with a respective one of the memory-device terminals, (ii) a plurality of internal terminals having respective unique bit significances, (iii) a switching unit, and (iv) a processor. The processor is configured to drive the memory device to communicate a predetermined sequence of bit patterns to the controller, and, in response to the sequence of bit patterns, drive the switching unit to connect each one of the external terminals to a respective one of the internal terminals having the bit significance of the memory-device terminal with which the external terminal is in communication. Other embodiments are also described.

Abstract: A method includes, in a memory system that includes a host and a storage device connected by a bus interface, assessing in the storage device a power supply state of the memory system. In the storage device a latency tolerance is selected for the bus interface based on the assessed power supply state. The selected latency tolerance is indicated from the storage device to the host, for application to the bus interface.
