However, the starting work of almost all information processing devices must be completed through the basic input/output system (basic input/output system; BIOS).

The Basic Input/Output System (BIOS) program is developed by the product developer before the product leaves the factory. After the development of the BIOS program is completed, the system R&D engineer must burn (flash) the BIOS program into a memory (such as ROM), and then assemble the memory with the BIOS program burned on the main board of the information processing device for error (Debug) ) detection, modify or update the BIOS program according to the detection result, when the BIOS program is damaged due to incorrect operation, burn the BIOS program to the memory again.

In order to facilitate the modification or update of the BIOS program, most product developers in the industry currently use an adapter (socket) to cooperate with the memory programmed with the BIOS program. The memory chip with the BIOS program burned is inserted into the adapter for error detection. If you want to modify or update the BIOS program, you need to unplug the memory chip from the adapter and use a programmer (programmer) or other The update tool modifies or updates the BIOS program in the memory chip.

In order to meet the development trend of miniaturization of semiconductor chip packaging, most memory chips (ROM) are packaged by TSOP (Thin Small Outline Package) packaging technology. Due to the very small size of the TSOP package, the pins (Pins) around the chip are very dense. (Generally at least 32Pin), if the memory chip is often plugged and unplugged on the adapter, the pins around the memory chip will be damaged, which may lead to a short circuit of the memory chip pins, and even the memory chip cannot be used. At the same time, the price of the adapter for the memory in the TSOP package is also quite expensive, which increases the cost of product development, and the adapter is not easy to maintain.
