METHOD FOR PERFORMING ACCESS OPERATION IN SYNCHRONOUS DYNAMIC RANDOM ACCESS MEMORY ARRAY AND INTEGRATED CIRCUIT DEVICE INCLUDING CIRCUIT FOR CONTROLLING COLUMN SELECTING SIGNAL
METHOD FOR PERFORMING ACCESS OPERATION IN SYNCHRONOUS DYNAMIC RANDOM ACCESS MEMORY ARRAY AND INTEGRATED CIRCUIT DEVICE INCLUDING CIRCUIT FOR CONTROLLING COLUMN SELECTING SIGNAL
PROBLEM TO BE SOLVED: To provide automatic delay technique for early read and write memory access operation in integrated circuit elements using a synchronous dynamic random access memory (SDRAM) elements and an incorporated SDRAM array.;SOLUTION: A circuit and method for controlling internal column selection ('Yi') and a data signal is provided. A column address strobe ('/CAS') signal can be made (active) earlier than the case in which conventional SDRAM array is used. In one embodiment, a column selection signal ('read' or 'write') is delayed until a signal generated after is made valid out of a corresponding pre-decoded column address signal or respective column clock signals.;COPYRIGHT: (C)2004,JPO
