Figure 4. The training process of the experimental demonstration.

Figure 4

(a) The activation function output value of the first class versus the iteration number using the write-verify scheme. The inset figure zooms in the several last steps. (b) The training process for programming without write-verify. (c) The initial and final conductance distribution comparison of the first row when updating with write-verify. Inset shows the final conductance map. (d) The conductance distribution of the first row and the conductance map for the case without write-verify.
