Data reading method of static memory

Abstract

The invention discloses a data reading method of a static memory, which belongs to the field of static memories, can cover all information of contacts by summarizing the information of the contacts into an information copy, is convenient to recommend to others, and protects the information by arranging an information transfer device between the static memory and a mobile phone system, when the mobile phone is powered off, an information copy can be sent to a mobile phone system, the trouble of re-recording after loss is omitted, the magnetic needle triggers the contact sensor according to theprinciple that the magnetic needle deflects due to a magnetic field around the power-on wire, and therefore the contact sensor sends a signal to the memory unit to enable the memory unit to work normally. The normal reading of the information copy under the power-on condition is achieved, under the power-off condition, a magnetic needle is made to deflect again according to the principle that opposite poles of the magnets attract each other, so that the magnetic needle is separated from the contact sensor, the contact sensor sends a signal to the memory unit to send the information copy to themobile phone memo system, and normal reading of information after next startup is facilitated.

Description

technical field [0001] The invention relates to the field of static memory, more specifically, to a data reading method of the static memory. Background technique [0002] Memory is a collection of storage units arranged in order of unit number. Each unit is composed of several ternary bits to represent the value stored in the storage unit. This structure is very similar to the structure of the array, so in the VHDL language, the memory is usually described by the array. According to the mechanism of saving data, it is divided into dynamic memory and static memory. Static memory relies on the two stable states of a flip-flop to hold information. Each bistable circuit stores a bit of binary code 0 or 1, and a memory chip contains many such bistable circuits. A bistable circuit is an active device that requires a power supply to work. As long as the power supply is normal, it can store information stably for a long time, so it is called a static memory. If the power is los...

Problems solved by technology

[0004] Smartphones all have the function of storing contact information. When we communicate with relatives and friends through social software, sometimes we recommend people in the mobile phone address book to the other party, but when entering information in the dialog box, we have to return to the address book Or the software interface to copy the contact information, and then return to the dialog box to paste the information, which is more troublesome, and the copied information is relatively simple and not comprehensive, and it is not convenient to use
