  • Publication number: 20160189786
    Abstract: A method for operating non-volatile memory device is provided. The method includes applying a first voltage level to a word line connected to a memory cell, applying a second voltage level to the word line for a first time period, performing a read operation on the memory cell during the first time period, and discharging the word line for a second time period to a third voltage level greater than or equal to about 1V. The method also includes performing an erase word line recovery on a plurality of blocks of memory cells during the erase operation, and prior to an erase phase. The erase word line recovery substantially discharges all word lines of the plurality of blocks of memory cells.

  • Patent number: 9142298
    Abstract: In a programming operation of a 3D stacked non-volatile memory device, an initial set of memory cells on a selected word line layer, involving fewer than all memory cells on a selected word line layer, are programmed first as a test case to determine optimal conditions for programming the remaining memory cells on the selected word line layer. For example, a number of program-verify iterations or loops which are needed to program the initial set of memory cells an initial amount is determined. This loop count is then stored, e.g., within the initial set of memory cells, within the remaining memory cells, within memory cells on a remaining word line layer, or in a data register, and programming of the initial set of memory cells continues to completion. Subsequently, the loop count is retrieved and used to determine an optimal starting program voltage for programming the remaining memory cells.

  • Patent number: 9135989
    Abstract: Methods and non-volatile storage systems are provided for recovering data during a programming of non-volatile storage. Program data that was originally stored in one set of latches may be preserved with a combination of two sets of latches. These two sets of latches may also be used to store verify status during programming of that program data. The original program data may be recovered by performing a logical operation on the data in the two sets of latches. For example, upper page data could be initially stored in one set of latches. While the upper page data is being programmed, that set of latches and another set of latches are used to store verify status with respect to the upper page data. If a program error occurs while the upper page data is being preserved, it may be recovered by performing a logical operation on the two sets of latches.

  • Patent number: 8842476
    Abstract: Methods and non-volatile storage systems are provided for determining erratically programmed storage elements, including under-programmed and over-programmed storage elements. Techniques do not require any additional data latches. A set of data latches may be used to store program data for a given memory element. This program data may be maintained after the programming is over for use in erratic program detection. In one embodiment, lockout status is kept in a data latch that is used to serially receive program data to be programmed into the storage element. Therefore, no extra data latches are required to program the storage elements and to maintain the program data afterwards.

  • Patent number: 8630118
    Abstract: Methods and non-volatile storage systems are provided for detecting defects in word lines. A “broken” word line defect may be detected. Information may be maintained as to which storage elements were intended to be programmed to a tracked state. Then, after programming is complete, the storage elements are read to determine which storage elements have a threshold voltage below a reference voltage level associated with the tracked state. By tracking which storage elements are in the tracked state, elements associated with other states may be filtered out such that an accurate assessment may be made as to which storage elements were under-programmed. From this information, a determination may be made whether the word line is defective. For example, if too many storage elements are under-programmed, this may indicate a broken word line.

  • Publication number: 20130243218
    Abstract: According to an embodiment, a switch of an audio output device selects any of an output of the buffer and an output of the zero data generation unit to output to the output port. The switch control unit controls the selection of the switch based on an instruction of an output control signal. The front address storage unit stores a setting value of a front address of the buffer. The offset value storage unit stores an offset value set in the buffer. The output address control unit outputs a value obtained by adding the offset value to the setting value of the front address as an output start address of the buffer.
