512 MB SDRAM MEMORY MODULE FOR APPLE POWERBOOK G4 400-500 MHZ [TITANIUM].Trans Intl. has announced the availability of the industry first low profile 512 MB SDRAM (Synchronous DRAM) A type of dynamic RAM (DRAM) memory chip that has been widely used since the late 1990s. SDRAM chips eliminated wait states by dividing the chip into two cell blocks and interleaving data between them. SO-DIMM See SODIMM.
SO-DIMM - Small Outline DIMM memory module for Apple's new Powerbook G4 400/500 Mhz [Titanium].
The Powerbook G4 Titanium has two memory expansion slots A receptacle inside a computer or other electronic system that accepts a printed circuit board. The number of slots determines future expansion. See PC data buses.
(hardware) expansion slot - A connector in a computer into which an expansion card can be plugged. for main memory expansion. Memory modules currently available in the channel limit upgrading the system's main memory to only 512 MB due to a small form factor module requirement in the system.
The new 512 MB SDRAM DIMM (Dual In-Line Memory Module) A printed circuit board that holds memory chips and plugs into a DIMM socket on the motherboard. See memory module.
DIMM - Dual In-Line Memory Module is specially designed to fit in the bottom and the top memory expansion slots of the Apple Powerbook G4 [Titanium], allowing users to upgrade the system's main memory up to 1 GB [Gigabyte] of RAM, which surpasses the current memory upgrade option of 512 MB. The 512 MB SDRAM memory module is 64-bit wide, unbuffered, 3.3v, 144-pin and PC-100 complaint. It conforms to Powerbook G4 electrical and mechanical specifications as outlined in Apple developer documentation.
Maximizing the Powerbook G4 Titanium with the Trans Intl. 512 MB DIMM memory upgrade enables the user to take full advantage of the system's performance with 100% compatibility with the recently released Firmware A category of memory chips that hold their content without electrical power. Firmware includes flash, ROM, PROM, EPROM and EEPROM technologies. When holding program instructions, firmware can be thought of as "hard software." See flash memory, ROM, PROM, EPROM, EEPROM and FOTA. Update 4.1.8, Mac OS 9.1 and Mac OS X.
