Title: Dynamic ram
Inventor: SHIBATA TAKESHI
IPC: G11C11/407
Filed: 1994-12-27
Abstract: PURPOSE: To stably synchronize an internal clock signal with an external clock signal even in a high frequency range by forming the internal clock signal in synchronization with the external clock signal and changing the variable frequency range of a PLL circuit by means of mode setting information. CONSTITUTION: An external clock signal CLK inputted through a clock input buffer is supplied to a phase/frequency comparator. An internal clock signal clk formed in a voltage controlled oscillator VCO is inputted to the comparator through a constant delay stage. The clock CLK is compared with the clock clk through the constant delay stage. Thus, by providing the constant delay stage and making the delay coincident with the signal delay time of the input buffer, the clock CLK is made to synchronize with the clock clk. Consequently, without taking the signal delay in the input buffer for fetching a clock signal into consideration, solely the operation in a high frequency complied with the operational upper limit frequency of the internal circuits is enabled.
