The storage module socket series products have multiple models and specifications to meet the application needs of multiple scenarios. The following is a detailed analysis of the specifications and applications of SODIMM, DIMM, M.2 and other storage module socket series products:
1、 SODIMM slot
The center to center spacing of DDR5 SODIMM slots is 0.5mm, with heights of 4mm and 5.2mm, and 262 digits. The memory bit width is dynamically divided from 64 bits to 32 bits * 2, which can achieve internal dual channel effect in a single memory, and the transfer rate can reach up to 6400 MT/s. The volume is reduced by about 50% compared to standard DIMMs, making it suitable for space constrained devices. The working voltage drops to 1.1V, with low power consumption and extended device battery life.
2、 DIMM slot
The center to center spacing of DIMM slots is 0.85mm, with 288 digits, and the transmission rate supports 3200 MT/s-6400 MT/s. There are different lengths of lock buckles available, including short locks, medium locks, and long locks. The installation methods include through-hole welding and surface mount. The working voltage of DDR4 is 1.2V, and the working voltage of DDR5 is 1.1V, with low power consumption and long battery life.
3、 M.2 connector
M. The distance between the two connector contacts is 0.5mm, and various heights ranging from 3.2mm to 8.5mm are available. It has key structures of A, B, E, and M. Supports single-sided and double-sided modules for more efficient reading and writing; Supports hot swapping, allowing for the replacement of solid-state drives without shutting down the device. The data transfer rate can reach up to 16GT/s, compatible with various communication protocols such as PCIe, USB, SATA, HSIC, UART, SMBus, Display Port, etc.
4、 PCIE slot
PCIE slots are available in fourth and fifth generations, with a center to center spacing of 1mm and 36, 64, 98, and 164 bits. The transmission rate is 16GT/s-32GT/s. In terms of interface and space occupation, they are backward compatible with PCIe Gen3.0/2.0/1.0 products. Meanwhile, PCIe slots support multiple communication protocols, mainly including PCIe 4.0, SAS, SATA, etc.
5、 Mini PCIe slot
The Mini PCIe slot has 52 bits and is available in various height specifications such as 4, 5.2, 5.6, 6.8, 7, 8, 9, and 9.9mm. The data transmission rate reaches 4Gb/s, which is more suitable for small devices while ensuring efficient transmission. Simultaneously supporting multiple communication protocols including USB, SATA, and PCI Express.
6、 SAS connector
The SAS connector adopts a serial full duplex communication protocol to achieve simultaneous bidirectional data transmission, with a transmission rate of up to 24Gb/s. The contact spacing is 1.27mm and the number of digits is 29. Compliant with SAS 4.0 specifications, supports SAS and SATA drives, and is perfectly backward compatible with SAS connector versions 3.0, 2.0, and 1.0, with hot swappable functionality.
7、 SATA connector
It has 7, 7+6, 7+15 and other different bits. The combination of different bits can realize simultaneous interpreting of signal and power supply. The bottom of the SATA interface is equipped with positioning columns and positioning harpoons, which can be more firmly installed on the PCB board. There are two installation methods available: through-hole welding and surface mount, with hot swappable function.
