Abstract:
Apparatuses, systems, and methods for counter based read clocks in stacked memory devices. An interface die provides a read command to a core die, which reads data with timing based on the read command provides that data to a read FIFO circuit of the core die. A delay time after providing the read command, the interface die begins providing a counter-based clock signal which operates an output of the read FIFO. The counter-based clock signal operates on a different time domain (e.g., a faster frequency) than the timing of the read command.
