Flash memory cards provide electrically erasable, programmable, read-only memory (EEPROM) that can be erased and reprogrammed in blocks instead of one byte at a time.
FLASH memory chips offer extremely fast access times, low power consumption, and relative immunity to severe shock or vibration. They do not need a constant power supply to retain their data.
Memory chips are internal storage areas in computers. Although the term “memory chip” commonly refers to a computer's random access memory (RAM), this product area includes many different types of electronic data storage. Computer memory stores data electronically in cells. Without memory chips, a computer could not read programs or retain data.
PCMCIA cards and accessories follow standards developed by the Personal Computer Memory Card International Association (PCMCIA), an international standards body and trade organization. PCMCIA cards, or PC cards as they are commonly known, were designed originally for adding memory to portable computers, but are now used in a variety of devices.
PCMCIA serial adapter cards provide one or more serial ports for a host computer. They interface with the host via a PCMCIA card bus and add RS232, RS422, or other types of serial ports.
SRAM chips use static random access memory (SRAM), a type of memory that is faster, more reliable, and more expensive than DRAM. Unlike DRAM, SRAM does not need to be refreshed in order to prevent data loss; however, SRAM requires more power than DRAM.
