摘要:
Data processing apparatus having an execution unit, a flow controller having a program counter, and a program counter sensor, which is connected to a data bus and to the program counter. The program counter sensor has a logic unit that ascertains the address of an instruction which is to be executed next from data transferred via the data bus, and a comparator, which compares the ascertained address with a content of the program counter and triggers an alarm signal if there is any discrepancy.

A device for protecting a data word against data corruption includes first and second determiners. The first determiner is configured to determine an error correction code cvA associated with a data word a so that cvA=aAT, with A being a generator matrix of a linear systematic base correction code, the columns of which enable performance of an x-bit error correction on replica of the data word a and the associated error correction code cvA. The second determiner is configured to determine an extended error correction code cvE so that (cvA|cvE)=aFT, with F being an extended generator matrix F = ( A E ) of an extended linear systematic correction code, the columns of which enable, using the extension error correction code cvE, performance of an y-bit error correction, with y>x, on a replica of the data word a and the associated error correction code cvA.

Some aspects of the present disclosure relate to a read circuit that uses a hybrid read scheme as set forth herein. In this hybrid read scheme, a state machine, at a first time in the read operation, sets a reference signal SRef to a first reference value to induce determination of a first comparison result. At a second subsequent time in the read operation, the state machine sets the reference signal SRef to a second reference value, which is based on the first comparison result. Setting the reference signal to the second reference value induces determination of a second comparison result. The first and second comparison results are then used to determine the digital value read from the memory cell.

The disclosed invention provides a structure and method for increasing the operating speed and reduce the overall programming time of a memory array. In one embodiment, the method and structure provided herein reduce the maximum write current consumption, for writing a plurality of data bits to a NVM array, by writing the data bits sharing an activated word line at different times (e.g., activating bit lines associated with an activated word line at different times). Specifically, the write operation of respective data bits, which individually utilize only a fraction of the overall write window of the bits, are interleaved so that the maximum write current of respective bits are offset in time from the maximum write current of another bit. This interleaving of data bit write windows allows a larger number of data bits to be written without exceeding system specifications (e.g., maximum current) reducing overall memory write time.

The invention relates to a data processing device with a functionally programmable logic circuit and a programming interface. An authorization control unit is provided, which protects the programming interface against an unauthorized access. This enables the functions of a semiconductor module to be changed in a customer-specific manner while preventing unauthorized entities from subsequently changing the functionality.

A multi-level sensing scheme compares the state of a multi-level storage cell with monotonously changing reference states, which are associated to different information values. That particular information value is identified to be the information stored in the multi-level storage cell, which has associated that reference state which, in a changing direction, firstly exceeds the state.
