Title: Apparatus for data store of memory circuit
Inventor: SHIN CHEOL HO
IPC: G06F12/16
Filed: 2001-03-26
Abstract: PURPOSE: A data storage of a memory circuit is provided to store data in a flash memory when electric power is interrupted by securing sufficient time for data storing. CONSTITUTION: A transformer(11) induces an input alternating current to a secondary part at a specific rate. A rectifier(41) rectifies and smoothes the power induced to the secondary part of the transformer. An electrostatic unit(14) transforms the voltage of the rectifier to the voltage of a level needed for each element of a system. A detection voltage input unit(42) divides the output voltage of the rectifier into the voltage of a specific level. A threshold voltage detector(43) detects a threshold voltage by comparing the output voltage of the detection voltage input unit to a reference voltage. If the interruption of electric power is decided by the threshold voltage detecting unit, data storage is completed within a minimal action voltage time. Therefore, data are stored in a flash memory without errors.
