128 KBytes capacity Magnetic Bubble Memory technology Non-volatile storage Rugged industrial design Data retention without power

Product description

The Siemens 6AB6580-0AA is a Memory Module, specifically the MMC 216 SPB 1, featuring Magnetic Bubble Memory technology with a capacity of 128 KBytes. This type of memory is known for its non-volatility and ruggedness, making it suitable for industrial environments.

Magnetic bubble memory was an older form of non-volatile storage. This module would have been used in industrial control systems where reliable data retention without continuous power was critical, such as in programmable logic controllers (PLCs) or specific automation hardware requiring persistent memory for program storage or parameter data.

Frequently asked questions

What is magnetic bubble memory, and why was it used in industrial applications?

Magnetic bubble memory is a type of non-volatile computer memory that stores data using localized magnetic regions called 'bubbles'. It was used in industrial applications because of its high reliability, immunity to dust and radiation, and ability to retain data without power, making it suitable for harsh environments.
