A42U0616 inputs: LCAS controls I/O0I/O7, UCAS controls I/O8 I/O15, UCAS LCAS function identical manner that either will generate internal signal. function timing determined first UCAS LCAS transition last transition high. Byte Read Byte Write controlled using LCAS UCAS separately. Read cycle performed holding signal high during operation. Write cycle executed holding signal during operation; input data latched falling edge whichever occurs later. data inputs outputs routed through common pins, with controlling direction. Page Mode operation 1024(1K) columns within selected randomly accessed high data rate. Page Mode cycle initiated with address latched followed column address latched While holding low, toggled strobe changing column addresses, thus achieving shorter cycle times. A42U0616 offers accelerated Fast Page Mode cycle through feature called Extended Data Out, which keeps output drivers during precharge time (tcp). Since data output after goes high, user required wait valid data appear before starting next access cycle. Data-out will remain valid long low, high; this only characteristic which differentiates Extended Data operation from standard Read Fast Page Read. memory cycle terminated returning both high. Memory cell data will retain correct state maintaining power accessing 1024(1K) combinations 10-bit addresses, regardless sequence, least once every 16ms through cycle (Read, Write) Refresh cycle -only, CBR, Hidden). Refresh cycle automatically controls addresses invoking refresh counter controller. Power-On initial application supply requires wait followed minimum eight initialization cycles containing clock. During Power-On, current dependent input levels recommended that track with held valid during Power-On avoid current surges. PRELIMINARY (June, 2001, Version 0.0) AMIC Technology, Inc.
