    摘要: A non-volatile memory may have memory portions, such as blocks or other granularities of units of memory, which may fail in actual use. These defective portions can be replaced with other portions which may, in some cases, be of corresponding size. In some embodiments, defects may be detected using a current sensor which detects the current drawn in actual operation. If an excessive current is drawn, this may be detected, the defective unit deactivated, and a replacement provided in its stead. This may result in the repair of a defect with little inconvenience to the user in some embodiments.

    摘要: An apparatus, such as a nonvolatile solid-state memory device, may, in some implementations, include access line bias circuitry to set a bias level associated with a deselected access line(s) of a memory core in response to mode information. In one approach, access line bias circuitry may use linear down regulation to change a voltage level on deselected access lines of a memory core. A memory access device, such as a host processor, may be provided that is capable of dynamically setting a mode of operation of a memory core of a memory device in order to manage power consumption of the memory. Other apparatuses and methods are also provided.

    摘要: Apparatus and methods for evaluating leakage currents of capacitances are described. Capacitances having excessive leakage currents may be disabled from use. An example apparatus includes a leakage detection circuit configured to be coupled to a capacitance block. The leakage detection circuit is configured to determine whether a leakage current of a capacitance of the capacitance block exceeds a current limit and is further configured to provide an output indicative of a status of the capacitance. A detection controller is coupled to the leakage detection circuit and a register, and the detection controller is configured to store data in the register indicative of the status of the capacitance based at least in part on the signal from the leakage detection circuit.

    摘要: Block-row decoders, memory block-row decoders, memories, methods for deselecting a decoder of a memory and methods of selecting a block of memory are disclosed. An example memory block-row decoder includes a plurality of block-row decoders, each of the block-row decoders having a decoder switch tree. Each block-row decoder is configured to bias a block select switch of the decoder switch tree with a first voltage while the block-row decoder is deselected and further configured to bias decoders switches of the decoder switch tree that are coupled to the block select switch with a second voltage while the block-row decoder is deselected, the second voltage less than the first voltage. An example method of deselecting a decoder of a memory includes providing decoder signals having different voltages to decoder switches from at least two different levels of a decoder switch tree while the decoder is deselected.
