An introduction to the analysis of memory interface types: The memory interface type of the gold finger is divided according to the number of conductive contacts on the finger of the memory stripe. The conductive contacts on the Goldfinger are also used to refer to pins (PIN numbers). The number of pins used for each interface type varies depending on the type of interface used for different memory. Notebook memory generally uses 144Pin, 200Pin interface, desktop memory is basically using 168P

signals can be delivered. The same interface with the DDR memory also uses the Dimm,sdram interface is slightly different, the SDRAM DIMM is 168Pin DIMM structure, the gold finger each side is 84Pin, the gold finger has two card ports, is used to avoid inserting the slot, the error will insert the memory backwards to cause the burning; DDR The DIMM uses a 184Pin DIMM structure with a 92Pin finger on each side and only one card on the gold finger. The difference between the number of cards is th

. STEP3: Finally, with a little bit of force, vertically insert the ram into the memory slot and press tight until the latch at both ends of the memory slot automatically latches the gap on both sides of the memory, as shown in Figure 3. Tip: On any motherboard that supports RDRAM, you can see that the RIMM memory slots appear in pairs. Since the Rdram memory strip is not able to be used alone, it must be a pair of appearance. RDRAM re

Rambus DRAM (also known as RDRAM) memory has the same pin as the DDR RAM memory, with 184 pins. But it looks completely different from SDRAM and DDR RAM. The first choice is to wrap a metal shield over the outside of the rdram to reduce electromagnetic interference. Attention to its pins, in the middle of the two notches near the design pin, these two gaps and SDRAM on the two gap is not the same OH. On both sides of the rdram memory, there is a gap.

If a company has been listed, we can see the future of the company from its stock price. In general, we can look at its PE and other indicators too much. Based on this, I plan to analyze RIM briefly. RIMM is listed on Nasdaq and the company's stock code is RIMM. Figure 1 shows the share price of the company in the last year. Currently, the latest price is RMB 147.55 (price ).

different memory IC, can be divided into the following 2 types of patterns: 72pin:72-sided Memory module is used to support 32-bit data processing volume. 30PIN:30-sided Memory module is used to support 8-bit data processing volume. DIMM (Dual in-line Memory Module): (168PIN) used to support 64-bit or wider bus, and only 3.3 volts, usually on 64-bit desktop computers or servers. The Rimm:rimm module is one of the main specifications for the next generation of memory modules, a memory module

Don't talk nonsense, look at the parameters.See the following links for details.Key features and specifications of the BlackBerry PlayBook include:* 7 "LCD, 1024x768 x, WSVGA, capacitive touch screen with full multi-touch and gesture support* BlackBerry Tablet OS with support for symmetric multiprocessing* 1 GHz Dual-core processor* 1 GB RAM* Dual HD Cameras (3 MP front facing, 5 MP rear facing), supports 1080p HD video recording* Video playback:1080p HD video, + H, MPEG, DivX, WMV* Audio Playba

and CPU socket close to the memory sockets, the advantage is: When the CPU fan out of the dust pollution can be cleaned, and the outlet is contaminated after the extremely difficult to clean. 4. Install memory, DIMM groove on both sides have a card teeth, when the memory gap is correct, and plug in the bit, the two teeth should automatically "bite" memory. DDR Memory gold finger only a notch, the gap between the asymmetry, corresponding to the DIMM memory slot on a convex edge, so the directio

, its maximum clock frequency should be 133 MHz, and its memory bus width should be 64 bit, with each clock data segment being 2. So (133x64X2)/8 = 2128 Mb/s. 2128 MB can be transferred in one second. Now you know why pc2100? Here is another example. Take pc800 RDRAM for calculation this time. The maximum clock frequency is 400 MHz, the memory bus width is 16 bits, and each clock data segment is 2, then the formula is (400x16x2)/8 = 1600 Mb/s. As you can see, the pc2100 DDR memory can provide up

transmission channel. The RAMBUS memory development has gone through three major phases, with first-generation and second-generation products known as "Base RAMBUS" and "Concurrent RAMBUS", which have reached 600MHz of data transfer rates and are used in some entertainment facilities such as Sony PS2), high-end graphics workstations and a number of high-performance graphics cards. The third generation of products called direct RAMBUS, whose enclosure is referred to as
