The present invention is described in detail below in conjunction with each embodiment shown in the drawings; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skills all belong within protection scope of the present invention according to these embodiment institute work energy, method or structural equivalent transformation or alternative.
Embodiment one
Please refer to the drawing 1 is to the first embodiment of the data-storage system of a kind of computing machine of the present invention shown in Figure 4.
Join shown in Figure 1ly, in the present embodiment, a kind of data-storage system 100 of computing machine comprises:
Some volatile memory 101, to form volatile memory component 10, some nonvolatile memories 401 of parallel organization, to form non-volatile storage component 40, some multiplexers 201 of parallel organization, to form the multiplexer assembly 20 of parallel organization.Concrete, the quantity of this multiplexer 201 equates with the quantity of volatile memory 101, and a memory controller 300.This memory controller 300 is connection multiplexing device 201 and nonvolatile memory 401 respectively.
In the present embodiment, this volatile memory 101 comprises at any time storer (SRAM) of dynamic random dynamic storage (DRAM) or static state, and is preferably dynamic random dynamic storage (DRAM).Certainly, this volatile memory 101 is not limited at any time storer (SRAM) of described stochastic and dynamic storer (DRAM) or static state, also can be the temporary data memory of the other types with the rear high speed save data that powers on.
Further, this nonvolatile memory 401 comprises nand flash memory or phase transition storage, and is preferably nand flash memory.Simultaneously, this nonvolatile memory 401 also can be resistive formula storer (RRAM), magnetic spin-torque storer (ST-RAM) or reluctance type storer (M-RAM).
Concrete, host memory controller 1 is by all multiplexers 201 of system bus 5 parallel joins of computer-internal; All multiplexers 201 of memory controller 300 parallel joins; Each multiplexer 201 connects a volatile memory 101, writes passage 15 to form a plurality of parallel data.
In the present embodiment, the data-storage system 100 of this computing machine also comprises: the power-supply controller of electric 500 of electric connection and energy storage device 501.Under the control of the power management module (not shown) that this power-supply controller of electric 500 can arrange in memory controller 300, between energy storage device 501 and volatile memory 101, set up and be electrically connected.In the normal power supply situation, be in open-circuit condition between energy storage device 501 and the volatile memory 101.Host power supply 2 can charge in energy storage device 501 by power-supply controller of electric 500.
Particularly, the data-storage system 100 of this computing machine exists two kinds of working conditions, i.e. normal power supply situation and power-down conditions.
Join shown in Figure 2ly, in the normal power supply situation, host power supply 2 can provide power supply to volatile memory 101 and memory controller 300 by biserial memory module 600.Data in the computing machine can be sent to all multiplexers 201 by the system bus 5 of host memory controller 1 by computer-internal, and writing volatile memory 101 by multiplexer 201, the data that write volatile memory 101 to form a plurality of data write passage 15.
By this set, given full play to the advantage of volatile memory 101 aspect hyperchannel, the processing of high-speed parallel data, the 100 pairs of data of data-storage system that improved this computing machine write the efficient of volatile memory 101 temporarily.Certainly, also can improve simultaneously computing machine to stability and the data security of the access of volatile memory 101.
Join shown in Figure 3ly, this multiplexer 201 is electrically connected memory controllers 300.After data write volatile memory 101, the data that multiplexer 201 can cut out rapidly with host memory controller 1 write passage 15, and between multiplexer 201 and memory controller 300, set up respectively parallel data and transfer passage 25, so that interim data of preserving in the volatile memory 101 are taken out, and transfer concurrently to memory controller 300, complete paired data is transferred step.
Join shown in Figure 4ly, in the present embodiment, this memory controller 300 is electrically connected a plurality of nonvolatile memories 401.Concrete, described nonvolatile memory 401 is electrically connected with memory controller 300, preserves passage 35 with the parallel data that form two or more.
This memory controller 300 is under the control of console controller 3, and the data communication device that will transferring in volatile memory 101 obtains is crossed some data and preserved passages 35 and be saved to concurrently nonvolatile memory 401, preserves and processes thereby finish data.
In conjunction with reference to Fig. 3 and shown in Figure 4, transfer to memory controller 300 and from memory controller 300 parallel being saved to the process of nonvolatile memory 401 at data parallel, host power supply 2 can provide power supply to memory controller 300 by biserial memory module 600.
