Abstract:
1. A method, comprising: storing data in a memory, which comprises multiple strings of analog memory cells arranged in a three-dimensional (3-D) configuration having a first dimension associated with bit lines, a second dimension associated with word lines and a third dimension associated with sections, such that each string is associated with a respective bit line and a respective section and comprises multiple memory cells that are connected to the respective word lines; for a group of the strings, evaluating respective values of a property of the strings in the group; calculating source-side voltages for the respective strings in the group, depending on the respective values of the property, and biasing respective source-sides of the strings in the group with the corresponding source-side voltages; and performing a memory operation on the strings in the group while the strings are biased with the respective source-side voltages.
