Abstract: Methods, apparatuses and systems related to tracking charge loss are described. An apparatus may include a tracking mechanism configured to make direct measurements for tracking charge loss in first-type cells. The apparatus may be configured to designate a set of the first-type cells as proxy for modeling charge loss at second-type cells having a different storage density than the first-type cells. The apparatus may use the tracking mechanism to make measurements on the proxy set of the first-type cells and translate the measurement to account for the charge loss at the second-type cells.

Abstract: Methods, systems, and apparatuses include sampling a memory subportion of a portion of memory, where the memory subportion includes multiple wordlines. A sampled voltage value for the memory subportion is determined based on the sampling. A maximum start voltage delta is received for the memory subportion, where the maximum start voltage delta is an estimated difference between the sampled voltage value and a lowest voltage value for the memory subportion. A start voltage to apply during programming of the memory subportion is determined using the sampled voltage value and the maximum start voltage delta.
