Crossbar Array Programming Using Piecewise-Constant Signals

Abstract
To program a crossbar array, we need to adjust the resistor conductance using a limited number of
control signals, which are voltages applied to the crossbar lines. Since the number of lines is significantly smaller than
the number of resistors, this is a multi-step procedure. At each step, the conductances of the selected resistors are
adjusted. The number of such resistors is no greater than the number of control signals. This inevitably changes the
conductivity of some half-selected resistors, too. These unwanted changes must be compensated for. We examined a
crossbar programming procedure using high-frequency piecewise-constant control signals. Our analysis involved a
simple resistive element model. We demonstrated that an arbitrary (within known limits) conductance matrix can be
programmed. At each step, a row or column of the crossbar array is generated or adjusted. We discussed the feasibility
and convenience of such a procedure
