ASProgrammer is a free, open-source, or donation-ware software tool designed specifically for reading and writing various types of non-volatile memory chips. Unlike generic flashing tools, ASProgrammer was built with a focus on:

is an open-source software alternative to the original CH341A programmer software, designed to read, write, erase, and verify data on various EEPROM and SPI flash chips. It is highly regarded for its stability and broader chip support compared to the default manufacturer tools. 1. Getting Started: Hardware & Setup
