Abstract

Techniques are provided for programming a multi-level self-selecting memory cell that includes a chalcogenide material. To program one or more intermediate memory states to the self-selecting memory cell, a programming pulse sequence that includes two pulses may be used. A first pulse of the programming pulse sequence may have a first polarity and a first magnitude and the second pulse of the programming pulse sequence may have a second polarity different than the first polarity and a second magnitude different than the first magnitude. After applying both pulses in the programming pulse sequence, the self-selecting memory cell may store an intermediate state that represents two bits of data (e.g., a logic '01' or a logic ‘10’).
