Read operations based on a dynamic reference

A method, comprising:

• receiving, from a host device, a read command for a set of memory cells where each memory cell of the set of memory cells is associated with a capacitive circuit comprising a first capacitor and a second capacitor;
• selectively coupling each capacitive circuit with a respective memory cell based at least in part on receiving the read command;
• coupling the second capacitor of each capacitive circuit to a reference voltage bus based at least in part on selectively coupling each capacitive circuit with the respective memory cell;
• comparing a charge stored by the first capacitor and the second capacitor of each capacitive circuit to a reference voltage on the reference voltage bus based at least in part on coupling the second capacitor of each capacitive circuit with the reference voltage bus;
• and
• outputting, to the host device, a set of values stored by the set of memory cells based at least in part on the comparing.

An apparatus, comprising:

• a set of memory cells;
• a set of capacitive circuits each configured to develop a signal of a memory cell from the set of memory cells during an access operation, each capacitive circuit comprising:
• a first capacitor configured to selectively couple with an access line associated with the memory cell;
• a second capacitor configured to selectively couple with the first capacitor;
• and
• a switching component coupled with the first capacitor and the second capacitor and configured to selectively couple with the first capacitor and the second capacitor;
• a reference voltage bus configured to selectively couple with the second capacitor of each capacitive circuit of the set of capacitive circuits during the access operation;
• and
• a sense component configured to compare a charge stored by the first and second capacitors of each capacitive circuit with a reference voltage on the reference voltage bus.
