Latest Patents

Irizarry’s recent patent work addresses the design and operation of nonvolatile memory systems.

“Read/write circuits for multi-story cross-point memory” describes control circuits that identify the story containing a selected memory cell and connect a sense amplifier to cells in different stories. The memory structure uses programmable resistive elements and shared word-line and bit-line layers.

“Bipolar decoders for nonvolatile memory with spike attenuation for threshold selector switches” addresses current spikes that can occur when threshold selector switches turn on during memory access. The disclosed approach biases local select switches to limit current from the decoding circuitry, helping reduce the risk of cell damage and unintended changes to stored data.
