Abstract: A multipurpose interlaced memory device functions in two different modes, synchronous and asynchronous. The memory uses a circuit for detecting address transitions by acting as a synchronous clock of the system for letting the control circuit of the memory device recognize the required access mode by enabling a comparison of the currently input external address with the one stored in the address counters of the two banks of memory cells. The memory device includes a buffer for outputting data. The buffer includes a circuit for pre-charging the output nodes to an intermediate voltage between the voltages corresponding to the two possible logic states, thus reducing noise and improving transfer time.

Abstract: An interleaved memory having an interleaved data path includes an array of memory cells divided into a first bank of memory cells and a second bank of memory cells, first and second arrays of sense amplifiers respectively coupled to the first and second bank of memory cells, and first and second read registers respectively coupled to the first and second arrays of sense amplifiers. A control and timing circuit is connected to the first and second arrays of sense amplifiers and has inputs for receiving externally generated command signals, and outputs for providing path selection signals and a control signal. A third register is connected to the first and second read registers and has inputs for receiving read data therein as a function of the path selection signals. An array of pass-gates are connected to the third register and are controlled in common by the control signal for enabling a transfer of the read data stored in the third register to an array of output buffers.

Abstract: A circuit for controlling a reference node in a sense amplifier switchable between an operating mode and a stand-by mode is provided. The reference node provides a reference voltage in the operating mode. The circuit may include circuitry for bringing the reference node to a starting voltage upon entry into the stand-by mode, circuitry for keeping the reference node at a pre-charging voltage in the stand-by mode, and circuitry for providing a comparison voltage closer to the pre-charging voltage than the starting voltage. Pulling circuitry may also be included for pulling the reference node toward a power supply voltage. Further, a controller may activate the pulling circuitry upon entering the stand-by mode, and disable the pulling circuitry when the voltage at the reference node reaches the comparison voltage.

Abstract: A multipurpose memory device suitable for a broader range of applications, whether requiring the reading of data in an asynchronous mode with random access (as in a standard memory) or in a synchronous sequential mode with sequential or burst type access, is capable of recognizing the mode of access and the mode of reading that is currently required by the microprocessor. The memory device self-conditions its internal circuitry as a function of such a recognition in order to read data in the requested mode without requiring the use of additional external control signals and/or implying a penalization in terms of access time and reading time compared to those which, for the same fabrication technology and state of the art design, may be attained with memory devices specifically designed for either one or the other mode of operation.
