  • Publication number: 20240288476
    Abstract: A power detector with wide dynamic range. The power detector includes a linear detector, followed by a voltage-to-current-to-voltage converter, which is then followed by an amplification stage. The current-to-voltage conversion in the converter is performed logarithmically. The power detector generates a desired linear-in-dB response at the output. In this power detector, the distribution of gain along the signal path is optimized in order to preserve linearity, and to minimize the impact of offset voltage inherently present in electronic blocks, which would corrupt the output voltage. Further, the topologies in the sub-blocks are designed to provide wide dynamic range, and to mitigate error sources. Moreover, the temperature sensitivity is designed out by either minimizing temperature variation of an individual block such as the v-i-v detector, or using two sub-blocks in tandem to provide overall temperature compensation.

As a result, charges stored in multiple programming sites of each flash transistor can be respectively sensed.

  • Publication number: 20240192895
    Abstract: A host system operates to manage a storage device. The host system initiates an abort of a command when the command has been fetched from a submission queue (SQ) of the host system and the SQ entry has been fetched from the SQ and the host system has not received a corresponding command completion response from the storage device. The host system sends an abort request to the storage device, and issues a cleanup request to direct a host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry to indicate completion of the abort request.
