DRAM Buffer
All digicams have a certain amount of fixed memory in them to facilitate image processing before the finished picture is stored to the flash memory card.
DRAM Buffer
Fixed memory used for image processing before the image is stored. Cameras with a burst mode have much larger DRAM buffers. This also makes them more expensive.

DRAM (Dynamic Random Access Memory)
When a digital camera, computer or other device, using DRAM, is powered down, this form of unstable memory is lost.

DRAM Buffer
Digicams must have some DRAM Buffer to process the image prior to writing to the memory card; the better cameras have more DRAM Buffer. Cameras with a "burst" mode require a large buffer of 32Mb or more.
Dynamic Range ...
(DRAM) memory in a computer must be "refreshed" - rewritten - regularly to prevent it from eventually going blank. Local variations in the manufacturing process of the CCD means that each photosite will have variations in ...
Battery life will be much longer, since the HDD rarely needs to spin up, since the huge amount of NVRAM will be able to buffer the data for long periods, even if power dies unexpectedly. Unlike today's DRAM computers, ...
Early high speed cameras used film to record the high speed events but today, high speed cameras are entirely electronic using either a charge-coupled device (CCD) or a CMOS image sensor, recording typically over 1000 frames per second into DRAM and ...
DRAM - Dynamic Random Access Memory A semiconductor read/write memory chip, in which the presence or absence of a capacitive charge represents the state of a binary storage element (zero or one). The charge must be periodically refreshed.
