PSEUDO SRAM COMPRISING PAGE ACTIVE CIRCUIT TO PREVENT ERROR OPERATION OF DATA READ, IN WHICH UNSTABLE PRECHARGE BETWEEN GLOBAL DATA BUS LINES IS PREVENTED

摘要

PURPOSE: A pseudo SRAM comprising a page active circuit to prevent an error operation of data read is provided to prevent unstable precharge between global data bus lines generated during a short transition of a page address. CONSTITUTION: A pseudo SRAM includes a row path(300) enabling a word line by detecting transition of an address signal and a column path(400) comprising a page address transition detection part(410) and a page active signal generation part(420) and a column signal control part(430). The page address transition detection part outputs a page address transition detection signal by detecting transition of a page address signal. The page active signal generation part generates a page active signal having a pulse period to precharge a global data bus line and a global data bus bar line sufficiently as to the page address transition detection signal. And the column signal control part enables a column selection signal as to the input of the page active signal.
