Title: Refresh control circuit for semiconductor memory device
Inventor: LEE CHEOL HA
IPC: G11C11/406
Filed: 2001-03-20
Abstract: PURPOSE: A refresh control circuit is provided to automatically generate a refresh signal by being embedded in a semiconductor memory device and synchronized with an external signal so that it can prevent a performance lowering of a memory system caused by frequent refresh operations. CONSTITUTION: The circuit comprises a refresh signal generator(11), a delay refresh signal generator(13), a logical circuit(15), a refresh counter(17) and a multiplexor(19). The refresh signal generator(11) generates a refresh signal(PREF) in response to refresh instruction signals(RASB, CASB, WEB) transmitted from a memory controller. The delay refresh signal generator(13) receives the refresh signal(PREF), and outputs a delayed refresh signal(PREF1) by delaying the refresh signal(PREF) by a certain time. The logical circuit(15) performs a logical summation operation on the refresh signal(PREF) and the delayed refresh signal(PREF1), outputs the logical summation result to the refresh counter(17) and functions a selection signal of the multiplexor(19). The refresh counter(17) generates sequentially low addresses to be refreshed in response to an output signal of the logical circuit(15). In a case that the output signal of the logical circuit(15) is activated, the multiplexor(19) blocks a path to an external address(EXT_ADD) and opens a path to a refresh address(REF_ADD) generated by the refresh counter(17) in response to an output signal of the activated logical circuit(15). So the multiplexor(19) outputs a word line enable signal(W/Li) to a word line of a corresponding memory cell for activating a word line selected by a refresh address(REF_ADD). In a case that the output signal of the logical circuit(15) is inactivated, the multiplexor(19) outputs a word line enable signal(W/Li) to a word line of a corresponding memory cell for activating a word line selected by the external address(REF_ADD).
