Specialty Memory Chips

Specialty memory chips are specialty or proprietary products and accessories related to memory chips. They are used in computers, embedded computing devices, game consoles, personal digital assistants (PDAs), smart phones, and other digital devices to increase the available memory for operations or digital storage. If large enough in terms of megabytes, a computer memory chip (also called a PC memory chip) can improve system processing significantly. RAM, DRAM, and FRAM memory chips are types of specialty memory chips. A PSP memory chip or Memory Stick Duo makes it easy to record and carry a variety of digital content, including music, video and photos. A flash memory chip is a form of electrically-erasable programmable read-only memory (EEPROM) or non-volatile read write memory (NVRWM) that, unlike a random-access memory (RAM) memory chip, retains stored data even when power is removed. Flash memory is used in universal serial bus (USB) flash drives, MP3 players, digital cameras and mobile phones.

Performance specifications for specialty memory chips include size in megabytes, transfer speeds, form factor, quality of manufacture (economy, general use, demanding use), power supply requirements, and cooling requirements. Specialty memory chips used in motion video or high quality audio should have higher transfer speeds. In advanced electronic metering systems, ferroelectric RAM (FRAM or FeRAM) can collect data for years without wearing out; operate with low power consumption (1 to 100 micro amps), and have fast access speed. Additional considerations may vary by application.

Specialty memory chips need to meet the requirements of the operating system (OS) or digital device in which they are used. For example, in a personal computer (PC), the RAM must be compatible with the front-size bus (for example PC100 or PC133). For computer printers, specialty memory chips are designed to be compatible for the particular make and model of printer.
