  • Patent number: 11881875
    Abstract: A memory includes a sequence of memory locations storing a corresponding sequence of state codes that specifying the shape of a waveform. The sequence of state codes is read from the memory and decoded by a long and toggle decoder circuit. The decoding operation generates a sequence of signal codes. When the state code is a long code, the sequence of signal codes includes same signal codes corresponding to a signal level of the waveform. When the state code is a toggle code, the sequence of signal codes includes a first signal code corresponding to one signal level of the waveform and a second signal code corresponding to another signal level of the waveform. A signal decode circuit then decodes the signal codes in the sequence of signal codes to generate the waveform for output which includes the signal levels corresponding to the decoded signal codes.

  • Patent number: 11875847
    Abstract: Memory devices such as phase change memory (PCM) devices utilizing Ovonic Threshold Switching (OTS) selectors may be used to fill the gap between dynamic random-access memory (DRAM) and mass storage and may be incorporated in high-end microcontrollers. Since the programming efficiency and reading phase efficiency of such devices is directly linked to the leakage current of the OTS selector as well as sneak-path management, a sense amplifier disclosed herein generates an auto-reference that takes into account the leakage currents of unselected cells and includes a regulation loop to compensate for voltage drop due to read current sensing. This auto-referenced sense amplifier, built utilizing the principle of charge-sharing, may be designed on a 28 nm fully depleted silicon-on-insulator (FDSOI) technology, provides robust performance for a wide range of sneak-path currents and consequently for a large range of memory array sizes, and is therefore suitable for use in embedded memory in high-end microcontroller.
