Selective call receiver with an intelligent memory system

DETAILED DESCRIPTION The invention thus has as its objective a pager intended to receive radio-broadcast message signals comprising call signal information and message information, said message information comprising one or several messages, said pager comprising a receiver intended to receive and to demodulate coded message signals, a memory arrangement for storing said message information, a decoder intended to decode such coded message signals and for selectively furnishing said message information to said memory arrangement, function control means capable of furnishing control signals to said memory arrangement and receiving therefrom message information which is stored therein, said pager being characterized in that said memory arrangement comprises internal processing means in order to control the reception of message information coming from said decoder.
Thus, the selected message information furnished by the decoder may be memorized by the memory arrangement without it being necessary to have instructions available from a microcomputer or a microprocessor outside such memory, this latter becoming thus in a manner of speaking "intelligent".
As a result, the selected message information may be directly memorized in real time in the intelligent memory arrangement which enables the microcomputer or microprocessor external to said memory means to accomplish other pager functions without the clock frequencies or processing speed being as high as in known pagers.
According to another characteristic of the invention, the pager may also be adapted in order to assure manipulation of stored message information in the memory arrangement so that deletion, copying and shifting of information thus memorized may be brought about within the memory arrangement, removing thus the limits imposed by such operation to the function control means, otherwise referred to as the pager microcomputer.
According to a still further characteristic of the invention, the pager may also be made capable of comparing message information received by the memory arrangement with previously stored information
