A solid-state disk (SSD) has a smart storage switch with a smart storage transaction manager that re-orders host commands for accessing downstream single-chip flash-memory devices. Each single-chip flash-memory device has a lower-level controller that converts logical block addresses (LBA) to physical block addresses (PBA) that access flash memory blocks in the single-chip flash-memory device.

A novel and useful apparatus for and method of distributed coexistence for mitigating interference in a single chip radio and / or a multi-radio (i.e. multi-transceiver) communications device. The invention enables coexistence ‘friendly’ radio IPs having frequency agility in that they are capable of shifting their clock frequencies thereby avoiding frequency bands of potential victim radios.

Each aggressor radio, based on information received from other radios, configures the root clock frequency of its RX and / or TX chain clock generation circuits.

Aspects of the invention for managing power in a single chip device may comprise, an internal finite state machine that, while in a communicating state, determines from within the single chip device whether a power management status is set and / or whether a first power management event is received.
