MX29GL640EHT2I-70G is a member of a family of memories referred to as Flash memories, or simply flash. In electronic systems and computing, flash memory is a form of non-volatile random-access memory that can be erased and reprogrammed in blocks instead of one byte at a time. It is one of the most commonly used type of non-volatile memory today.

In its most basic form, flash memory is a semiconductor integrated circuit (IC) chip, which is divided into an array of memory cells, each of which is divided into memory blocks. The memory blocks can be individually accessed, read, written and erased using logic circuitry, making it possible to quickly rewrite the data stored in the cells. In order for the data to be stored, each cell must be physically "programmed" by injecting electrons into the semiconductor material.

The MX29GL640EHT2I-70G is an example of a NOR flash memory, which stands for "Not-OR" flash memory. NOR flash is the most common type of flash memory and is used to store large quantities of data, including code, application data, and operating systems. NOR flash differs from NAND flash memory in that it is organized in blocks instead of pages and can be read in parallel instead of a page-by-page basis as with NAND flash.

In terms of applications, the MX29GL640EHT2I-70G can be used in a variety of electronic devices, including cameras, video recorders, cellular phones, PDAs, PCs and notebooks. It is also commonly used in memory cards and USB flash drives. These devices make use of the chip’s high-speed read and write capabilities and can benefit from its low cost per-bit storage.

The MX29GL640EHT2I-70G works by taking advantage of the two different voltages (2.7V and 1.8V) present in the memory sector of the chip. When a program or a write command is given, the voltage in the cell blocks is reduced below a specific threshold for a specific amount of time. This causes electrons to be injected into the semiconductor material and stored in the cells, thus writing data in the memory. When a read command is given, the voltage within the memory sector is increased and the stored electrons form a current flowing from the semiconductor material to the external circuit, thus “reading” the stored information from the memory.

Overall, the MX29GL640EHT2I-70G is an efficient, cost-effective non-volatile memory chip that can be used in a variety of applications. With its high-speed read and write capabilities, and its ability to store large amounts of data in a relatively small size, it is an ideal choice for many electronic devices. Additionally, its NOR-type architecture make it well suited for storing large amounts of code and data.
