BBSRAM

   Also found in: Acronyms 0.01 sec.
BBSRAM
(Battery Backed SRAM) SRAM memory that is backed up with a lithium battery in the event of power failure. "Discrete BBSRAM" places SRAM chips on a small printed circuit board (PCB) along with the battery and switchover circuit. The PCB is typically around 60 square inches. "BBSRAM modules" encapsulate the SRAM, battery and circuitry into chip packages that are smaller than the discrete BBSRAM boards. See nvSRAM and solid state drive.



BBSRAM Memory Packages BBSRAM provides battery-backed, high-speed SRAM memory. Although somewhat slower than BBSRAM, Ramtron's non-volatile F-RAM memory eliminates the battery and related circuitry in a considerably smaller footprint.

FRAM is superior to BBSRAM in that there is no need for an on-board or external battery to back up data and is inherently highly reliable due to its monolithic form factor.
