SST38VF6404B-70-5I-CD

Memory: SST38VF6404B-70-5I-CD

The SST38VF6404B-70-5I-CD is a type of non-volatile memory (NVM) chip. This chip is manufactured by LSI Logic and is available in a variety of capacities, from 256Kb to 4Mb. It is an extension of the SST38VF series of NVM chips, which are specifically designed for use in mobile computing applications.

Application Field

The SST38VF6404B-70-5I-CD is most commonly used in mobile computing applications. It is used to store software and data which needs to be retained even when the device is powered off. It is also used as a means to expand the memory capacity of a device beyond that of the main memory. For example, it is often used in smartphones and tablets to store frequently used applications and data.

Working Principle

The SST38VF6404B-70-5I-CD chip is an NVM chip which means that it retains data even when the power is off. This is achieved by using a floating gate transistor, which stores the information electrically. This allows the chip to retain its data even when its power source is removed.

The chip is programmed by writing data to its EEPROM cells. These cells are divided into logical blocks, which can be further divided into sectors. This structure allows for efficient writing of the data to the chip, as each logical block and sector can be addressed independently.

Reading data from the chip is done by a process known as burning. This process involves sending a voltage spike to the cell in question, which causes the data stored in it to be read and stored in a register. This data can then be used by the device.

Conclusion

The SST38VF6404B-70-5I-CD is a type of non-volatile memory chip. It is commonly used in mobile computing applications and is used to store software and data which needs to be retained even when the device is powered off. Data is written to and read from the chip using the processes of programming and burning.
