Interface techniques for stacked memory architectures

A method, comprising:

• transmitting, by logic circuitry of a first semiconductor die in communication with a plurality of first interfaces of the first semiconductor die, first signaling to the plurality of first interfaces;
• configuring, at each of the plurality of first interfaces, one or more operations associated with the plurality of first interfaces based on the plurality of first interfaces receiving the first signaling;
• transmitting, based on configuring the one or more operations, respective second signaling from at least one of the plurality of first interfaces to at least one of a plurality of second interfaces in communication with the plurality of first interfaces, the plurality of second interfaces included in one or more second semiconductor dies that are coupled with the first semiconductor die;
• and
• accessing, by the at least one of the plurality of second interfaces, one or more memory arrays of the one or more second semiconductor dies based on the at least one of the plurality of second interfaces receiving the respective second signaling.

An apparatus, comprising:

• a first semiconductor die, comprising:
• a plurality of controllers operable to couple with a host processor;
• and
• a plurality of first interfaces each coupled with a controller of the plurality of controllers and comprising respective first circuitry configured to receive first signaling from the controller and to transmit second signaling based on the received first signaling;
• and
• one or more second semiconductor dies coupled with the first semiconductor die, the one or more second semiconductor dies comprising:
• a plurality of memory arrays;
• and
• a plurality of second interfaces each coupled with a respective first interface and comprising respective second circuitry operable to receive the second signaling from the respective first interface and to perform one or more operations on a respective set of one or more of the plurality of memory arrays based on the received second signaling.
