• Aerospace and Robotics.

The device is also used in applications requiring high speed operations and high data throughput, such as workstations and servers.

Working Principle

The AT49BV002-12TI memory chip is based on the 2T-SRAM architecture. This type of memory employs injection-coupled transistors (ICTs), which act as an active pull-down on the memory cell. This allows for faster, more efficient reads and writes of data. Furthermore, the increased coupling between the cells, which eliminates capacitive loading, also allows for higher speed operation.

In addition, the device features a built-in self-timed write cycle, allowing for consecutive writes without any additional circuitry. This feature makes the device ideal for applications where sequential writes occur frequently. Furthermore, the device is capable of a high write and erase speed, making it suitable for high speed applications.

The AT49BV002-12TI memory chip also features built-in error correction, which helps to reduce errors caused by ambient noise or interference. The device also has built-in write protection and over-erase protection, ensuring reliable operation in harsh environments. Finally, the chip offers a reset function which can be used to reset the device back to its initial state.
