    摘要: An MRAM memory is proposed which gives a maximum read-out signal. This is advantageous for high-speed sensing of the MRAM bits. In an MRAM memory with magnetoresistive memory cells linked together to form logically organized rows and columns, It is obtained by, at least during writing, connecting write bitlines of two adjacent rows or columns with each other, so as to write inverse data values in two adjacent memory cells. In this way, a return path for the writing current is provided in a small loop, which enhances EMC behavior.

    摘要: The present invention relates to a method and circuit arrangement for performing an error correction in a memory arrangement in which a redundancy system is used. The addresses of faulty cells are recorded redundantly by applying a corresponding coding. Then, an error correction is applied to the faulty-address information before it is compared to an externally applied address. Thereby, errors due to faulty redundancy addresses can be prevented.

    摘要: The invention relates in particular, though not exclusively, to an integrated circuit with an embedded non-volatile memory with floating gate (10). According to the invention, at least two poly layers of equal or at least substantially equal thickness are used for this device. The first poly layer, poly A, is for the floating gate (10) and for the gates (22) of NMOS and PMOS in the logic portion of the circuit. The second poly layer, poly B, serves exclusively for the control electrode (21) above the floating gate. If so desired, a third poly layer may be deposited for both the control electrode and the logic gates, so that the thicknesses of these electrodes, and thus their resistances, are given desired values. Problems like overetching and bridging during saliciding are prevented in that the control electrode and the logic gates have the same thickness.

    摘要: In programmable memories of the EPROM or EEPROM type, a row and/or column of test memory cells are added to the matrix of rows and columns of non-volatile memory cells for the testing of the peripheral circuits which select and read the memory cells. The test memory cells have a very short write time as compared with the non-volatile memory cells and may be of the dynamic (or volatile) type. The write time for a memory cell of the EPROM or EEPROM may be, for example, 10 msec. The write time for a dynamic memory cell, however, is 100 nsec. The time required for testing the peripheral circuits can therefore be reduced by a factor of 80 (for a 16 Kbit memory) or higher (for memories larger than 16 Kbits).

    摘要: Field effect transistors having a short channel length are desirable for carrying out logic operations at a high speed. However, they are then not capable of withstanding the comparatively high programming and erasing voltage at which an (E)EPROM has to be operated. During the programming cycle the field effect transistors are kept in the current-nonconducting state, while recording the logic information obtained by the logic operations, the "fast" transistors are nevertheless capable of withstanding the comparatively high voltage.
