Abstract:
A method for capacitance coupling parameter estimation is disclosed. Step (A) of the method determines a plurality of voltages in a plurality of memory cells of a nonvolatile memory in response to a plurality of writes to the memory cells. The voltages are determined in each of a plurality of cases related to inter-cell interference. Step (B) generates a system of equations of a capacitance coupling model in response to the voltages from all of the cases. Step (C) generates one or more parameters in response to the system of equations. The parameters include one or more couplings between a perturbed memory cell and a plurality of neighboring memory cells adjacent to the perturbed memory cell.
