  • REUSE OF BAD BLOCKS FOR TASKS IN A MEMORY SUB-SYSTEM
    Publication number: 20230333762
    Abstract: A failure of a block among a set of blocks of a memory device of a memory subsystem is detected. Based on detecting the failure of the block, the block is evaluated for reuse. The block is designated for reuse based on a result of the evaluating of the block. The block is allocated to a task based on the block being designated for reuse.

  • Data-structure based dynamic program targeting control
    Patent number: 11210154
    Abstract: Feedback relating to errors in memory operations on a plurality of memory cells is received by a memory sub-system. At least one processing level corresponding to a program distribution is updated based on the feedback to adjust an error measure between pages of the plurality of memory cells and to adjust a read window budget within a page of the plurality of cells. The updating of the at least one processing level is based on information for the at least one processing level that is stored in a data-structure.

  • Power reduction technique for current mode digital-to-analog converters
    Patent number: 5635935
    Abstract: A video DAC for driving video displays with reduced power dissipation is presented. This is accomplished using a dual driver circuit connected to a current mirror, the dual driver comprising a strong driver and a weak driver. The dual driver permits switching current between the video load and a dummy load. The current to the dummy load is disabled during periods when the video signal remains steady for a predetermined period of time. The dual driver, using the weak driver, disables the current to the dummy load during video blanking and synchronization periods. This scheme substantially reduces the power dissipation in the DAC.
