Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, . Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Models were now the 1500 half-ton, 2500 three-quarter-ton, and 3500 dual-rear-wheel only one-ton in both two- and four-wheel drive. Ram 1500s offered both short 6.5-foot (2.0 m) and long 8-foot (2.4 m) cargo beds on both regular and extended Club Cabs, Ram 2500s offered only long beds with regular cabs or a choice of beds on Club Cabs, and Ram ...
There is only a little difference between a dual rank UDIMM and two single-rank UDIMMs in the same memory channel, other than that the DRAMs reside on different PCBs. The electrical connections between the memory controller and the DRAMs are almost identical (with the possible exception of which chip selects go to which ranks).
Dual-channel-enabled memory controllers in a PC system architecture use two 64-bit data channels. Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of each other, and many motherboards use both by using DDR memory in a dual-channel ...
The Chevrolet Silverado/GMC Sierra 3500, Ford F-350, and Ram 3500 are known as "one ton" pickups. [ 26 ] Similar schemes exist for vans and SUVs (e.g. a 1-ton Dodge Van or a 1 ⁄ 2 -ton GMC Suburban), medium duty trucks (e.g. the 1 1 ⁄ 2 -ton Ford F-550 ) and some military vehicles, like the ubiquitous deuce-and-a-half .

However, it can open two memory pages at once, which simulates the dual-port nature of other video RAM technologies. The earliest known SGRAM memory are 8 Mbit [6] chips dating back to 1994: the Hitachi HM5283206, introduced in November 1994, [34] and the NEC μPD481850, introduced in December 1994. [35]
