  • Patent number: 10964372
    Abstract: Methods, systems, and devices for memory cell biasing techniques are described. A memory cell may be accessed during an access phase of an access operation. A pre-charge phase of the access phase may be initiated. The memory cell may be biased to a voltage (e.g., a non-zero voltage) after the pre-charge phase. In some examples, the memory cell may be biased to the voltage when a word line is unbiased and the memory cell is isolated from the digit line.

  • Patent number: 10896712
    Abstract: Methods, systems, and devices for biasing techniques, such as open page biasing techniques, are described. A memory cell may be accessed during an access phase of an access operation, for example, an open page access operation. An activate pulse may be applied to the memory cell during the access phase. The memory cell may be biased to a non-zero voltage after applying the activate pulse and before a pre-charge phase. The pre-charge phase of the access phase may be initiated after biasing the memory cell to the non-zero voltage.

  • Patent number: 10410737
    Abstract: Methods, systems, and devices for recovering fatigued ferroelectric memory cells are described. Recovery voltages may be applied to a ferroelectric memory cell that is fatigued due to repeated access (read or write) operations. The recovery voltage may have a greater amplitude than the access voltage and may include multiple voltage pulses or a constant voltage. The recovery operation may be performed in the background as the memory array operates, or it may be performed when a host device is not actively using the memory array. The recovery operations may be performed periodically or may include discrete series of pulses distributed among several instances.
