Accurate Pcm Crosspoint Emulator And Its Use On Eigenvalues Calculation

Phase-change memory (PCM) is the most mature candidate technology to be used in in-memory computing systems. For being able to experiment with large-scale PCM configurations, we developed an accurate and precise hardware PCM cell model that emulates the basic intrinsic impairments of the PCM technology, and we used it in a NxN PCM crosspoint emulator for matrix-vector multiplication. In this work, we present details of the architecture of a PCM cell emulator and its use in a PCM crosspoint. We also demonstrate how the PCM crosspoint is used for eigenvalue calculations of symmetric positive values matrices.
