A 16GB [1] DDR4 SO-DIMM module by Micron. DDR4 memory is supplied in 288-pin dual in-line memory modules (DIMMs), similar in size to 240-pin DDR3 DIMMs. DDR4 RAM modules feature pins that are spaced more closely at 0.85 mm compared to the 1.0 mm spacing in DDR3, allowing for a higher pin density within the same standard DIMM length of 133.35 mm ...
Kindle Fire showing components, back cover removed. The Amazon Fire, formerly called the Kindle Fire, is a line of tablet computers developed by Amazon.Built with Quanta Computer, the Kindle Fire was first released in November 2011, featuring a color 7-inch multi-touch display with IPS technology and running on Fire OS, an Android-based operating system.
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. Three SDRAM DIMM slots on a ABIT BP6 computer motherboard. A DIMM ( Dual In-Line Memory Module ) is a popular type of memory module used in computers.
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. The first memory modules were proprietary designs that were specific ...
DDR5 has about the same 14 ns latency as DDR4 and DDR3. [7] DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. [8] [3] DDR5 also has higher frequencies than DDR4, up to 8GT/s which translates into 64 GB/s (8 gigatransfers/second × 64-bits/module / 8 bits/byte = 64 GB/s) of bandwidth per DIMM.
DDR2 and DDR3 increased this factor to 4× and 8×, respectively, delivering 4-word and 8-word bursts over 2 and 4 clock cycles, respectively. The internal access rate is mostly unchanged (200 million per second for DDR-400, DDR2-800 and DDR3-1600 memory), but each access transfers more data.
The number of physical DRAMs depends on their individual widths. For example, a rank of ×8 (8-bit wide) DRAMs would consist of eight physical chips (nine if ECC is supported), but a rank of ×4 (4-bit wide) DRAMs would consist of 16 physical chips (18, if ECC is supported). Multiple ranks can coexist on a single DIMM.
The Government of Pakistan has prioritized Information technology as a key component of its efforts to establish an "Information age" within the country. [12] Significant progress has been made in developing efficient computerized e-government systems for major departments, including the police, law enforcement agencies, and district administration.
