In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [ 1 ] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers , workstations , and servers .
Two types of DIMMs: a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). The SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has one. Also, each module has eight RAM chips, but the lower one has an unoccupied space for the ninth chip; this space is occupied in ECC DIMMs.
A test with DDR and DDR2 RAM in 2005 found that average power consumption appeared to be of the order of 1–3 W per 512 MB module; this increases with clock rate and when in use rather than idling. [14] A manufacturer has produced calculators to estimate the power used by various types of RAM. [15]
2011: In January, Samsung announced the completion and release for testing of a 2 GB [1] DDR4 DRAM module based on a process between 30 and 39 nm. [28] It has a maximum data transfer rate of 2133 MT/s at 1.2 V, uses pseudo open drain technology (adapted from graphics DDR memory [29]) and draws 40% less power than an equivalent DDR3 module. [28 ...
The time to read the first bit of memory from a DRAM with the wrong row open is T RP + T RCD + CL. Row Active Time T RAS: The minimum number of clock cycles required between a row active command and issuing the precharge command. This is the time needed to internally refresh the row, and overlaps with T RCD. In SDRAM modules, it is simply T RCD ...
MotorTrend , celebrating its 75th anniversary this year, selected the all-new Ram 1500 pickup as its 2025 top truck of the year. A combination of a new powerful engine, comfortable interior, and ...
With two transfers per cycle of a quadrupled clock signal, a 64-bit wide DDR3 module may achieve a transfer rate of up to 64 times the memory clock speed. With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of ...
