  • Publication number: 20210407605
    Abstract: Apparatus and methods are described to program memory cells and verify stored values programmed into the cells. The next stage in stored memory can be moved to the current verification iteration when certain conditions are met. Verification can include counting bits that exceed a voltage value for a stage being verified to produce a bit count number and determining if the bit count number for the stage being verified meets a threshold value. If the bit count number does not meet the threshold, the verification process can continue with a current verify iteration and thereafter move to a next verify iteration. If the bit count number does meet the threshold, the process can add a next stage to the current verify iteration and thereafter move to a next verify iteration.

  • Publication number: 20210405920
    Abstract: Power and/or current regulation in non-volatile memory systems is disclosed. Peak power/current usage may be reduced by staggering concurrent program operations in the different semiconductor dies. Each set of one or more semiconductor dies has an earliest permitted start time for its program operation, as well as a number of permitted backup start times. The permitted start times are unique for each set of one or more semiconductor dies. There may be a uniform gap or delay between each permitted start time. If a semiconductor die is busy with another memory operation at or after its earliest permitted start time, then the program operation is initiated or resumed at one of the permitted backup times. By having permitted backup times, the memory system need not poll each semiconductor die to determine whether the semiconductor die is ready/busy in order to determine when a die should start a program operation.

  • Publication number: 20210375339
    Abstract: Aspects of a storage device including a memory and a controller are provided which allow for reduction of current during program operations using pre-charge timing control based on an inhibit bit line count acquired from data latches. When the inhibit bit line count is within a bit line count range, the controller pre-charges bit lines in memory during a first time period to a first target voltage, and when the inhibit bit line count is outside the bit line count range, the controller pre-charges the bit lines during a second, earlier time period to a second, smaller target voltage. The controller is thus configured to reduce current and minimize operation overlaps in the earlier time period during the middle of the program operation where current is highest. Thus, a balance in power consumption and performance may be achieved during program operations using timing control.

  • Publication number: 20210375349
    Abstract: Aspects of a storage device including a memory and a controller are provided which allow for reduction of current in open blocks during read operations using multi-stage read voltage control. The controller determines whether a block is open or closed. If the block is closed, the controller causes a read voltage to be applied to one of the block's word lines. If the block is open, the controller causes a read voltage to be applied to another of the block's word lines in a number of stages. The controller further causes a read voltage to be applied to another word line of the open block in a different number of stages. Thus, read voltages for open blocks may ramp in multiple stages in contrast to read voltages for closed blocks, as well as ramp in different numbers of stages for different word lines in open blocks.

  • Publication number: 20210375338
    Abstract: Aspects of a storage device including a memory and a controller are provided which allow for reduction of current during program operations using pre-charge ramp rate control based on an inhibit bit line count acquired from data latches. When the inhibit bit line count is within a bit line count range, the controller pre-charges bit lines in memory at a first ramp rate to a first target voltage, and when the inhibit bit line count is outside the bit line count range, the controller pre-charges the bit lines at a second, faster ramp rate to a second, smaller target voltage. The inhibit bit line count may increase throughout a program operation, and the bit line count range may be configured for the middle of the program operation where current is typically high. Thus, a balance in power consumption and performance may be achieved during program operations using ramp rate control.

  • Publication number: 20210375371
    Abstract: Aspects of a storage device including a memory and a controller are provided which allow for reduction of current in open blocks during read operations using read voltage ramp rate control. The controller determines whether a block is open or closed. If the block is closed, the controller causes a read voltage to be applied to one of the block's word lines at a first ramp rate. If the block is open, the controller causes a read voltage to be applied to another of the block's word lines at a slower, second ramp rate. The controller further causes a read voltage to be applied to another word line of the open block at a different, third ramp rate. Thus, read voltages for open blocks may ramp slower than read voltages for closed blocks, as well as ramp at different rates for different word lines in open blocks.

  • Patent number: 11189351
    Abstract: A memory apparatus and method of operation is provided. The apparatus includes a block of memory cells arranged in strings and connected to word lines overlying one another in a stack. The block is divided into first and second sub-blocks programmed as a whole in a sub-block mode and includes a particular group connected to a particular word line. A control circuit determines whether the particular group being read is in the second sub-block when operating in the sub-block mode. The control circuit also determines whether one of the first and second sub-blocks is not programmed based on whether the particular group being read is in the second sub-block. The control circuit applies an adjusted read voltage to the word lines of the one of the first and second sub-blocks while reading the particular group based on whether the one of the first and second sub-blocks is not programmed.
