Abstract
Apparatuses, master-slave detect circuits, memories, and methods are disclosed. One such method includes performing a master detect phase during which a memory unit in a memory group is determined to be a master memory unit, determining at each memory unit its location relative to other memory units, and determining at each memory unit its location in the memory group based on a total number of slave memory units and its location relative to other memory units.
Claims19
An apparatus, comprising:
- a memory unit of a memory group including a comparator unit configured to, as part of each initialization procedure, determine a location of the memory unit in the memory group based on a comparison of a number indicative of memory units in the memory group and a number indicative of a position of the memory unit relative to a position of a last memory unit of the memory group.
A method comprising:
- determining whether a memory unit of a memory group is a master memory unit;
- responsive to a determination that the memory unit of the memory group is a master memory unit, providing a pulse signal to other memory units of the memory group to initiate a location calculation phase;
- and
- responsive to a determination that the memory unit is a slave memory unit, during the location calculation phase, determining a position within the memory group based on a count of pulses received from a preceding memory unit of the memory group and a count of pulses received from a succeeding memory unit of the memory group.

A method comprising:
- receiving, at a memory unit of a memory group, a first signal indicative of a position of the memory unit relative to a position of a last memory unit of the memory group from a succeeding memory unit of the memory group;
- providing the first signal to a preceding memory unit of the memory group;
- receiving a second signal indicative of a total number of memory units in the memory group;
- and
- determining a location of the memory unit in the memory group based on the first signal and the second signal.
