Memory is a vital part of any computing system and is used extensively in everyday life. The DS1225 AB-85+ is a non-volatile static random access memory (SRAM) which is used in many industries, ranging from medical to military applications. This article will explore the application fields and working principle of the DS1225AB-85+.

What is DS1225AB-85+?

The DS1225AB-85+ is a 4K x 8 parallel non-volatile static random access memory (SRAM) device which uses Double Metal Gate (DMG) technology. This type of SRAM can store two bytes of data for each location. What makes this device valuable for designers is its non-volatility, which means that it can store data even when the power is off. The traditional way of creating non-volatile memory was through expensive battery-backed solutions, so this device found a place in many data protection systems which could preserve data and settings even during a power outage.

Application fields and potential applications

The application fields for the DS1225AB-85+ are numerous, as the device can be used in a wide range of industries and to support a variety of products. Some of these application fields include medical, automotive, industrial, military, communications, and consumer electronics. In these fields, the device is used for a variety of applications such as nonvolatile storage for critical parameters, on-board storage for electronically reconfigurable products, and nonvolatile memory replacing EEPROMs in data recorder applications.

The device is also used in portable electronics to store settings, program code, and communication data. Furthermore, it includes advanced security features which make it suitable for many safety-critical systems, such as industrial and medical automated systems which must remain powered off for extended periods of time without losing their data. This type of memory device is also used in military applications, such as aircraft and missiles, where it may be necessary to store critical setting parameters and configuration information.

Advantages over other Memory Devices

The advantages of the DS1225AB-85+ over other types of memory devices are the high speed, low power consumption, and high endurance. The device can operate at clock speeds of up to 25MHz, while drawing a low current of 50mA. In addition, the device has a low power consumption of 12mW and up to 10,000 erase/write cycles, making it ideal for applications that require frequent access operations.

Working Principle

The device uses a floating gate array and is based on Double Metal Gate (DMG) technology. This type of memory uses an additional gate, or ‘floating’ gate, to store two bytes of information. The information is written onto this gate by applying an electrical charge passing through the device, and then discharged by applying an electrical discharge to the gate. This process enables the device to store information, even when it is powered off, which is why it is referred to as \'non-volatile\' memory.

The DS1225AB-85+ is an excellent choice for applications where low power consumption, high performance, and data security are important factors. Its nonvolatile memory feature makes it suitable for applications where data protection is needed and its low power consumption makes it suitable for use in portable electronics. Furthermore, its high endurance and fast clock speeds make it an ideal choice for applications that require frequent access operations.
