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.
Double Data Rate 2 Synchronous Dynamic Random-Access Memory (DDR2 SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) interface. It is a JEDEC standard (JESD79-2); first published in September 2003. [2] DDR2 succeeded the original DDR SDRAM specification, and was itself succeeded by DDR3 SDRAM in 2007.
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 .
The Chrysler A engine of 318 cu in (5.2 L) was the smallest V8 option; and all of Chrysler's larger engines, with the notable exception of the Chrysler Hemi engine, were available as factory options. The original design was built until the spring of 1965, when the facelifted, single-headlamp version arrived.
M44, M45, and M46 simply designated the long single tandem, long double tandem, and extra long double tandem chassis for the M35 2 + 1 ⁄ 2-ton series of trucks; there was also a short tandem chassis without an M designation. These cab/chassis would serve as the basis for many more specialized variants.
51.2 GB/s DDR SDRAM uses double-data-rate signalling only on the data lines. Address and control signals are still sent to the DRAM once per clock cycle (to be precise, on the rising edge of the clock), and timing parameters such as CAS latency are specified in clock cycles.
The 1 + 1 ⁄ 4 ton M880-series was based on the Dodge W200, a 3 ⁄ 4 ton capacity 4×4 civilian/commercial truck. The 880/890 had a 2,500 lb cargo rating, enabling it to have a 5 ⁄ 4-ton load rating. The similar 1 + 1 ⁄ 4 ton M890-series was based on the Dodge D200, a 3 ⁄ 4 ton capacity 4×2 civilian/commercial truck.
