摘要： Methods, systems, and devices for ferroelectric memory plate power reduction are described. A plate line may be coupled with a voltage source, a capacitor, and one or more sections of a bank of ferroelectric memory cells. During a write operation, the capacitor may be discharged onto the plate line and the resulting voltage may be adjusted (e.g., increased) by the voltage source before writing one or more memory cells. During a write-back operation, a capacitor associated with one or more memory cells may be discharged onto the plate line and stored at the capacitor. The charge may be re-applied to the plate line and adjusted (e.g., increased) by the voltage source during the write-back.

摘要： The present disclosure includes apparatuses and methods for partitioned parallel data movement. An example apparatus includes a memory device that includes a plurality of partitions, where each partition of the plurality of partitions includes a subset of a plurality of subarrays of memory cells. The memory device also includes sensing circuitry coupled to the plurality of sub arrays, the sensing circuitry including a sense amplifier. A controller for the memory device is configured to direct a first data movement within a first partition of the plurality of partitions in parallel with a second data movement within a second partition of the plurality of partitions.

摘要： Methods, systems, and devices for cell voltage accumulation discharge are described. One or more sections of a bank of ferroelectric memory cells may be coupled with one or more access lines. By activating one or more switching components, one or more sections (that may include a memory array and/or a driver) of memory cells may be isolated. When isolated, a voltage may be applied across an access line associated with the section to activate an access device of each memory cell. By activating a switching component of a respective memory cell, a capacitor of the memory cell may be discharged and then the isolated section may be coupled with the plurality of access lines.

摘要： The present disclosure includes apparatuses and methods related to accessing data in memory. One example method comprises storing data associated with a first operation in a first sense amplifier responsive to receiving a request to perform a second operation, and performing the second operation associated with a row of memory cells while the data associated with the first operation is being stored in the first sense amplifier.
