CIRCUIT FOR IMPROVING DATA READ SPEED IN FLASH MEMORY

摘要

PURPOSE: A circuit is provided to write data stably by enabling a counter in a synchronization to normal clocks or converted clocks according to a write mode or a read mode. CONSTITUTION: A circuit comprises: an inverter(100) for inputting a read control signal (READ CON) to a counter control part(31), controlling a first and second counter(32, 33), and outputting an external clock(CLK) inversely; a multiplexer(200) for selectively outputting the external clock(CLK) and the inverted clock from the inverter(100) by the read control signal(READ CON); and a latch part(300) for latching data of an input/output buffer(2) at the time of outputting data by an application of the external clock(CLK).
