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’).

Claim (Index 24):
A memory apparatus, comprising:\n a word line; a bit line; a self-selecting memory cell having a bottom surface coupled with the word line and a top surface opposite the bottom surface, the top surface coupled with the bit line, the self-selecting memory cell comprising a tapered profile between the bottom surface and the top surface; and a controller operable to:\n identify a first logic state for the self-selecting memory cell configured to store more than two logic states; \n apply a first pulse with a first polarity to the self-selecting memory cell to program the self-selecting memory cell with a second logic state different than the first logic state; \n apply a second pulse with a second polarity to the self-selecting memory cell to program the self-selecting memory cell with the first logic state, wherein the second polarity is different than the first polarity and the first amplitude is greater than the second amplitude, wherein the first logic state is an intermediate state; and \n store the first logic state in the self-selecting memory cell based at least in part on applying the first pulse with the first polarity and the second pulse with the second polarity.
