LPDDR4
Low-Power Double Data Rate (LPDDR), also known as LPDDR SDRAM, is a type of synchronous dynamic random-access memory (SDRAM) that consumes less power than other random access memory designs and is thus targeted for mobile computing devices such as laptop computers and smartphones. Older variants are also known as Mobile DDR, and abbreviated as mDDR. Modern LPDDR SDRAM is distinct from DDR SDRAM, with various differences that make the technology more appropriate for mobile applications. LPDDR technology standards are developed independently of DDR standards, with LPDDR4X and even LPDDR5 for example being implemented prior to DDR5 SDRAM and offering far higher data rates than DDR4 SDRAM. Bus width In contrast with standard SDRAM, used in stationary devices and laptops and usually connected over a 64-bit wide memory bus, LPDDR also permits 16- or 32-bit wide channels. The "E" and "X" versions mark enhanced versions of the specifications. They formalize overclocking the memory arra ...

Synchronous Dynamic Random-access Memory
Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal. DRAM integrated circuits (ICs) produced from the early 1970s to the early 1990s used an ''asynchronous'' interface, in which input control signals have a direct effect on internal functions delayed only by the trip across its semiconductor pathways. SDRAM has a ''synchronous'' interface, whereby changes on control inputs are recognised after a rising edge of its clock input. In SDRAM families standardized by JEDEC, the clock signal controls the stepping of an internal finite-state machine that responds to incoming commands. These commands can be pipelined to improve performance, with previously started operations completing while new commands are received. The memory is divided into several equally sized but independent sections called ''banks'', allowing the device to operate on a memor ...

DDR5 SDRAM
Double Data Rate 5 Synchronous Dynamic Random-Access Memory (DDR5 SDRAM) is a type of synchronous dynamic random-access memory. Compared to its predecessor DDR4 SDRAM, DDR5 was planned to reduce power consumption, while doubling bandwidth. The standard, originally targeted for 2018, was released on July 14, 2020. A new feature called Decision Feedback Equalization (DFE) enables input/output (I/O) speed scalability for higher bandwidth and performance improvement. DDR5 has about the same latency as DDR4 and DDR3. DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. DDR5 also has higher frequencies than DDR4, up to 9600 MT/s is currently possible, 8200 MT/s translates into around 66 GB/s of bandwidth. Using liquid nitrogen 13000 MT/s speeds were achieved. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017. On November 15, 2018, SK Hynix announced completion of its first DDR5 RAM chip; running at 5.2 GT/s at 1.1 V ...

Samsung Galaxy Tab 7
Samsung Group (; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest (business conglomerate) in South Korea. Samsung has the world's fifth-highest brand value. Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Group. Key affiliates of Samsung include Samsung Electronics, the world's largest information te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
