Abstract: A variety of applications can include a memory device having a memory die designed to control a power budget for a cache and a memory array of the memory die. A first flag received from a data path identifies a start of a cache operation on the data and a second flag from the data path identifies an end of the cache operation.

In various embodiments, the controller can be operable to feedback a signal to a memory controller external to the memory die to adjust an operating speed of an interface from the memory controller to the memory die. Additional devices, systems, and methods are discussed.

Abstract: Disclosed are systems and methods involving memory-side write training to improve data valid window. In one implementation, a method for performing memory-side write training may comprise delaying a rising edge or a falling edge of a first data signal, delaying a rising edge or a falling edge of a second data signal, and aligning the two adjusted signals to reduce a window of time that the data signals are not valid and thereby improve or optimize the data valid window (DVW) of a memory array. According to implementations herein, various edges of data signals and clock signals may be adjusted or delayed via dedicated trim cells or circuitry present in the data paths located on the memory side of a system.

Abstract: Examples described herein can be used to calibrate resistances provided by pull-up and pull-down circuits in an output driver circuit. A first reference voltage can be determined and applied to set a resistance level of a pull-up circuit to a desired level. A code for activating one or more transistor in the pull-up circuit can be determined against the first reference voltage. For a pull-down circuit, a second reference voltage can be set a resistance level of the pull-down circuit to a desired level. The resistance level of the pull-down circuit can be set to equal to the resistance level of the pull-up circuit. A second code can be set for activating one or more transistor in the pull-down circuit. The first and second reference voltages can be represented by index values. The code and second code can be stored for use by the pull-up circuit and pull-down circuit. Re-calibration of the pull-up and pull-down circuits can be performed to determine codes using the first and second reference voltages.
