Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility. FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory .
The notch on DDR2 DIMMs is in a different position from DDR DIMMs, and the pin density is higher than DDR DIMMs in desktops. DDR2 is a 240-pin module, DDR is a 184-pin module. Notebooks have 200-pin SO-DIMMs for DDR and DDR2; however, the notch on DDR2 modules is in a slightly different position than on DDR modules.
One should definitely be careful buying 1 GB memory modules, because all these variations can be sold under one price position without stating whether they are ×4 or ×8, single- or dual-ranked. There is a common belief that number of module ranks equals number of sides.
Notch positions on DDR (top) and DDR2 (bottom) DIMM modules. On the bottom edge of 168-pin DIMMs there are two notches, and the location of each notch determines a particular feature of the module. The first notch is the DRAM key position, which represents RFU (reserved future use), registered , and unbuffered DIMM types (left, middle and right ...
DDR4 RAM operates at a voltage of 1.2 V and supports frequencies between 800 and 1600 MHz (DDR4-1600 through DDR4-3200). Compared to DDR3, which operates at 1.5 V with frequencies from 400 to 1067 MHz (DDR3-800 through DDR3-2133), DDR4 offers better performance and energy efficiency. DDR4 speeds are advertised as double the base clock rate due ...
Memory controller with differential serial connections to DDR2 FB-DIMMs. The AMB is visible in the center of each DIMM. A Fully Buffered DIMM (FB-DIMM) is a type of memory module used in computer systems. It is designed to improve memory performance and capacity by allowing multiple memory modules to be each connected to the memory controller ...
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 ...
Flipkart slowly grew in prominence and was receiving 100 orders per day by 2008. [16] Flipkart acquired WeRead in 2010 from Lulu.com that helped it build its foundational strength which was the digital retail of books. This space was otherwise only shared by very limited number of players at that time in the market, such as Landmark and ...
