Patent ID: 11935601
Assignee: SUPERMEM, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method of accessing a memory, comprising:
accessing a word line of a memory array;
while accessing the word line of the memory array:
accessing a first bit line corresponding to a sense amplifier;
sampling and holding a first developed voltage associated with a state of a first memory bitcell at the word line and the first bit line;
accessing a second bit line corresponding to the sense amplifier; and
sampling and holding a second developed voltage associated with a state of a second memory bitcell at the word line and the second bit line;

providing, to the sense amplifier, the held first developed voltage;
generating a reference voltage;
sensing, with the sense amplifier, the held first developed voltage, wherein:
the second bit line is accessed while the held first developed voltage is sensed, and
sensing the held first developed voltage comprises amplifying a difference between the held first developed voltage and the reference voltage;

providing, to the sense amplifier, the held second developed voltage; and
sensing, with the sense amplifier, the held second developed voltage, wherein sensing the held second developed voltage comprises amplifying a difference between the held second developed voltage and the reference voltage.
