Abstract: A method includes: creating L2P tables while programming virtual blocks (VBs) across memory planes; creating an L2P bitmap for each VB, the L2P bitmap identifying logical addresses, within each L2P table, that belong to each VB; creating a VB bitmap for each L2P table, the VB bitmap identifying virtual blocks to which the respective L2P table points; creating an updated VB bitmap for a first L2P table based on changes to the first L2P table; determining that an entry in the VB bitmap is different than the entry in the updated VB bitmap, the entry corresponding to a particular VB; identifying an L2P bitmap corresponding to the particular VB; changing a bit within the identified L2P bitmap for an L2P mapping corresponding to the entry; and employing the identified L2P bitmap to determine L2P table(s) of the respective L2P tables that contain valid logical addresses for the particular VB.

Abstract: A method for predicting if a flow over a smooth ramp surface will separate from the ramp surface, wherein the ramp surface has a slope that is everywhere non-positive along the length of the ramp surface relative to the flow at the inflow end of the ramp surface includes i) dividing the height of the ramp surface by the length of the ramp surface to determine a height-to-length ratio of the ramp surface, ii) identifying a maximum slope magnitude of the ramp surface, iii) calculating a maximum normalized slope by dividing the maximum slope magnitude of the ramp surface by the height-to-length ratio of the ramp surface, and calculating a critical ramp slope as a linear function of the height-to-length ratio of the ramp surface. If the maximum normalized slope is greater than the critical ramp slope, the method predicts the turbulent boundary layer will separate from the ramp surface.
