Abstract: A system can include a plurality of sequencers each configured to provide a number of sequenced output signals responsive to assertion of a respective sequencer enable signal provided thereto. The system can include chaining circuitry coupled to the plurality of sequencers. The chaining circuitry can comprise logic to: responsive to assertion of a primary enable signal received thereby, assert respective sequencer enable signals provided to the plurality of sequencers in accordance with a first sequence; and responsive to deassertion of the primary enable signal, assert the respective sequencer enable signals provided to the plurality of sequencers in accordance with a second sequence.

Abstract: A system can comprise a memory device and sequencing circuitry configured to provide enable signals to a number of voltage regulators in association with providing sequenced power signals to the memory device. The system can include voltage threshold detection circuitry configured to: detect primary supply voltage events; and responsive to detecting a primary supply voltage event, deassert a timer enable signal provided to timing circuitry. The timing circuitry is configured to, responsive to the deassertion of the timer enable signal: deassert a primary enable signal provided to the sequencing circuitry; and maintain the primary enable signal in a deasserted state for a particular amount of time prior to reasserting the primary enable signal.
