Delay circuit with reduced Vdd dependence and semiconductor memory device having the same

摘要

The delay circuit has a voltage source which supplies voltage to a delay chain comprising a pair of inverters (401,404), transistors (406,407), resistor (402), NAND gate (405) and capacitors (403,408), in response to the input signal (IN). Independent claims are also included for the following: (1) delay circuit arrangement; and (2) delay circuit manufacturing method.
