  • Publication number: 20130250692
    Abstract: Systems and techniques for performing write operations on non-volatile memory are described. A described system includes a memory structure including non-volatile memory cells that are arranged on word lines and bit lines and a microcontroller that is communicatively coupled with the memory structure. The memory structure can include non-volatile memory cells that are arranged on word lines and bit lines. The microcontroller can be configured to receive data to write to the memory structure, write the data to the memory structure using a selected word line of the word lines, detect a failure to write the data, apply, based on the failure, a negative bias voltage to one or more unselected word lines of the word lines during a negative bias period, and write the data to the portion of the memory cells using the selected word line during the negative bias period.

  • Publication number: 20110170354
    Abstract: This document discusses among other things, a system comprising a host controller, an Input/Output buffer, and a memory device. The memory device is coupled to the host controller and is configured to receive a read command from the host controller. The non-volatile includes an interface control logic, which is in communication with a non-volatile memory. The interface control logic includes a latency programming circuit coupled to the non-volatile memory and the Input/Output buffer. The latency programming circuit stores at least one value corresponding to dummy byte delays to be provided at the non-volatile memory prior to transferring data from the non-volatile memory during a read operation.
