How many pins does a Rimm have?
A RIMM has a 184-pin connector and an SO-RIMM module has a 160-pin connector.
How many pins are there in Sdrdimm?
Variants
| SDRAM | SDR SDRAM | |
|---|---|---|
| DIMM | 100-pin | 168-pin |
| SO-DIMM | N/A | 144-pin |
| MicroDIMM | N/A | 144-pin |
| ^ Jump up to: a b c with different notch positions |
How many pins are in a DDR2 DIMM?
240 pins
Chips and modules For use in computers, DDR2 SDRAM is supplied in DIMMs with 240 pins and a single locating notch.
How many pins do DDR2 and DDR3 have?
240-pin DIMM (same size as DDR2 but are electrically incompatible with DDR2 DIMMs and have a different key notch location). DDR3 SO-DIMMs have 204 pins.
What are the two configurations of SIMM chips?
Single-sided and double-sided configurations are available.
How many bits of parity information is found in a 72 pin SIMM?
(The board that houses the chips often costs more than the DRAM chips.) Enter the 72-pin SIMMs, with 72 pins on each card. One of these is four times wider than a 30-pin SIMM, which is 8-bits wide (see Figures 7.5 and 7.6)….The 72-Pin SIMM.
| Configuration | Memory |
|---|---|
| 16 MB x 32 | 64 MB, no parity |
| 16 MB x 36 | 64 MB, parity |
How many pins are there in a SIMM?
Figures 6.3 through 6.9 show a typical 30-pin (8-bit) SIMM, 72-pin (32-bit) SIMM, 168-pin SDRAM DIMM, 184-pin DDR SDRAM (64-bit) DIMM, 240-pin DDR2 DIMM, 240-pin DDR3 DIMM, and 184-pin RIMM, respectively. The pins are numbered from left to right and are connected through to both sides of the module on the SIMMs.
How many pins are there in a DIMM?
DDR2 and DDR3 DIMMs have 240 pins, two notches on each side, and one near the center of the contact area. All DIMMs are either 64 bits (non-ECC/parity) or 72 bits (data plus parity or error-correcting code [ECC]) wide.
What is the difference between a Simm and DIMM?
It differs from a dual in-line memory module (DIMM), the most predominant form of memory module today, in that the contacts on a SIMM are redundant on both sides of the module. SIMMs were standardised under the JEDEC JESD-21C standard.
What are the different types of RIMM pins?
By far the most common type is the 16/18-bit version. The 32-bit version was introduced in late 2002, and the 64-bit version was introduced in 2004. The standard 16/18-bit RIMM has 184 pins, one notch on either side, and two notches centrally located in the contact area.
