Problems solved by technology

Therefore, later users cannot increase the capacity or bandwidth of volatile memory and non-volatile memory according to their usage needs
[0006] Secondly, if the memory stick is pulled out on the user's existing computer motherboard and replaced with a hybrid storage device in the prior art, the user's existing memory stick cannot be used, which increases the economic burden of the user and increases waste of resources

[0045] Specifically, the controller 101 is electrically connected to four first storage elements 102 in parallel, and the controller 101 is electrically connected to four multiplexers (MUX) 103 in parallel.

[0046] The controller 101 is an FPGA-based chip or an ASIC with logic control functions.

[0047] Specifically, the multiplexer (MUX) 103 is a high-speed signal switching device, which has a plurality of high-speed electro...

Embodiment 2

[0060] Please refer to figure 2 , Figure 10 , Figure 12 and Figure 13 Another specific embodiment of a storage device of the present invention is shown.

[0061] Compared with the first embodiment, the main difference of this embodiment is that the storage device 100 also includes a first expansion port 110 provided on the first printed circuit board 10, and the first expansion port 110 is connected to the controller 101 electrical connection.

[0062] In this embodiment, the first expansion port 110 is a high-speed interface (HSTC), and the first expansion interface 110 includes a data pin 1101 and a power pin 1102, which are used to electrically connect a plurality of flash memory 1021 in parallel. figure 2 The first storage element 102 in is the same type of non-volatile memory; preferably, the flash memory 1021 is NAND.

[0063] Through this setting, the user can arbitrarily increase the number of parallel data read-write channels formed by the first storage elem...

Embodiment 3

[0066] Please refer to image 3 and Figure 10 Another specific embodiment of a storage device of the present invention is shown.

[0067] Compared with the specific implementation shown in the second embodiment, the main difference of this embodiment is that the first expansion port 110 is electrically connected to the first interface 104 and used to connect to several DRAMs (Dynamic Random Access Memory) 2011 .

[0068] In this embodiment, the capacity of the second storage element 201 and the bandwidth of the second storage element 201 can be increased through the first expansion port 110 , thereby improving the performance of the storage device 100 .

[0069] With the continuous improvement of the manufacturing process level of dynamic random access memory (DRAM), the user can only replace the second circuit without replacing the electronic components such as the first circuit board 10 and its electrically connected controller 101. board 20 or by increasing the capacity ...

Abstract

The invention discloses a storage device which comprises a first printing circuit board and a second printing circuit board. The first printing circuit board is provided with a controller, a plurality of first storage elements, a plurality of multiplexers, first interfaces and second interfaces, wherein the first storage elements and the multiplexers are electrically connected with the controller respectively, and the first interfaces and the second interfaces are electrically connected with the multiplexers respectively. The second printing circuit board is provided with a plurality of second storage elements and third interfaces, wherein the third interfaces are electrically connected with the first interfaces mutually in a movably containing mode. In the storage device, the first printing circuit board with a nonvolatile memory, the controller and the multiplexers is mutually and electrically connected with the second printing circuit board with a volatile memory through the third interfaces and the first interfaces in a movably containing mode so as to form the storage device, and resource waste is reduced. Meanwhile, a first expanding port on the first printing circuit board improves convenience for performing expanding on the volatile memory and / or the nonvolatile memory in the storage device by users.

Description

technical field [0001] The present invention relates to the technical field of computer storage, in particular to a storage device used in a computer storage system which can be detachably arranged. Background technique [0002] The data storage system of a computer is mainly based on a volatile memory (such as a DRAM). Volatile memory is characterized by fast operation speed, small unit bit area, and low price. However, when the computer is powered off, the data temporarily stored in the volatile memory will disappear. [0003] The United States announced the authorized patent "HYBRID NONVOLATILE RAM", and the authorized announcement number US8074034B2 discloses a hybrid memory. Under the control of the controller and the power controller, when the computer system is suddenly powered off, the volatile memory can be dynamically saved. The data of the computer is quickly saved to the non-volatile memory, thereby effectively protecting the "metadata" in the computer system, t...
