Working Principle

In order to understand the working principle of the W29GL256SH9B TR, it is necessary to look at how the memory is structured. The memory is divided into tiny sections called “cells”, and each cell can hold one unit of data. The data is written to the cells by applying voltage to them, and the data can be read from the cells by applying voltage to them.

For the purpose of writing data to the cells, a write circuit is provided with the memory. This write circuit will activate when a certain voltage is applied, and will write the data to the cells. In terms of reading data from the cells, a read circuit is also provided with the memory. This read circuit will activate when a certain voltage is applied, and will read the data from the cells.

The W29GL256SH9B TR also includes an on-chip controller, which is responsible for controlling the memory and the write and read circuits. This controller will ensure that the data is written and read correctly, and will also monitor the voltage levels to ensure they stay within the specified levels.

Conclusion

The W29GL256SH9B TR is a Flash memory with a density of 256 Mb. It is commonly used for embedded systems such as mobile phones, radios, and automotive entertainment. The W29GL256SH9B TR operates by writing and reading data to and from tiny cells, and includes a write circuit, read circuit and an on-chip controller to ensure that data is written and read correctly.
