    Abstract: A method and apparatus for reducing the amount of RAM required while maintaining fast data access. Data records are often saved in nonvolatile memory in order to maintain the contents of the data records even when the circuit is powered down. In the present invention each record in the nonvolatile RAM collection of data records is input to a function H(x) that outputs a tag value. The calculated tag value is saved in predetermined memory locations in RAM. Each calculated tag is shorter in length than the record saved in nonvolatile RAM. Therefore less RAM is required to save one tag value for each data record than is required to save the entire collection of data records in RAM. The value of H(y) is calculated when a data record entry corresponding to y is desired. Then the value of H(y) is compared to all the values in the tag value table. If a match is found, the corresponding record from its location in non-volatile RAM is retrieved and compared to y. If the values do not match the tag value table is searched for another location matching H(y). The result is a very fast comparison with the contents of nonvolatile RAM requiring only a minimal amount of RAM.

    Abstract: A wireless communication device (100) may include a display (122), an incoming-call alert device (130), a call processor (128) and other features. A scheduler (126) selectively generates control signals to provide for intelligent control of the manner of operation of the features of a wireless communications device (100). In one embodiment, a receiver (110) receives a time-related data message from a remote location to set a timer (124) with the current time, including the date. The current time is compared with predetermined time-periods and the scheduler (126) generates alternate control signals to control the features during predetermined time-periods.

    Abstract: Un método para un acceso rápido a la información que minimiza la cantidad de memoria rápida requerida que comprende: la creación de un grupo de registros de información individuales; almacenar el grupo de registros de información en memoria; generar (308) un valor tag para cada registro de información en el grupo; almacenar (318) los valores tag en ubicaciones predeterminadas de la memoria rápida; recibir (320) una entrada que requiera una búsqueda del grupo de registros de información; generar (322) un valor tag de entrada correspondiente al valor de entrada; comparar (344) el valor tag de entrada con los valores tag almacenados en la memoria rápido; y recuperar (348) del grupo de registros de información el registro de información correspondiente al valor tag que coincida con el valor tag de entrada; caracterizado por comparar (350) el registro de información recuperado con el valor de entrada.
