    摘要: A circuit to screen for defects in an addressable line in a non-volatile memory array comprises a current mirror circuit which has a plurality of mirroring stages. The current mirror circuit is connected to the addressable line and receives a control signal and mirrors the control signal to provide a current to the addressable line. In a preferred embodiment, the current mirror circuit provides a high voltage current to the addressable line which is used to effectuate an operation such as program or erase to the memory cells connected to the addressable line. The change in state or the absence of change in state of the memory cells connected to the addressable line can be used to screen for defects in the addressable line.

    摘要: A digital multilevel memory system includes a charge pump and a voltage regulator for generating regulated high voltages for various memory operations. The charge pump may include a plurality of boost circuits to boost the output of the charge pump during a fast start up. Afterwards, the boost circuits are disabled to allow the charge pump to generate high voltages without boosting. The boost circuits may be successively enabled to boost the voltage. The boost circuits may be loadless. The voltage regulator may operate in an open loop and may include a resistive divider as a reference voltage for regulating the high voltage from the charge pump. The charge pump may include spread spectrum pump clocking to reduce electromagnetic inference for capacitor or inductor on-chip charge pumping.

    摘要: A Unified Memory may store multiple types of content such as data or fast code or slow code. The data or code may be stored in separate arrays or in a common array. In an array, a tag bit may indicate the type of content such as data or fast code or slow code or single level or multilevel content. Tag bit may indicate communication interface or IO driver type. Sense amplifiers may be configurable based on the type of data being read. A Flash Security Measure is used to protect a protected memory area. A Flash Security Key is used for authentication and authorization a particular memory area. A XCAM (e.g., CAM) array is included in the Unified Memory. Unified Memory Concurrency is included.
