  • Single-ended phase-change memory device and reading method
    Patent number: 10978146
    Abstract: A phase-change memory device, comprising: a memory array of PCM cells, a variable current generator, and a sense amplifier. The current generator comprises a reference array of PCM cells programmed in SET resistance state. The phase-change memory device further comprises a decoder for addressing each cell of the reference array so that a respective plurality of SET current signals is generated through the plurality of reference cells; and a controller configured to receive at input said SET current signals, select a number of SET current signals having the lowest current values among the plurality of SET current signals, calculate a mean value of said lowest current values, and adjust the reference current to be lower than said mean value.
    Type: Grant
    Filed: October 24, 2019
    Date of Patent: April 13, 2021
    Assignee: STMicroelectronics S.r.l.
