Disclosed are a storage device and method, an electronic device, and a storage medium. The device includes: a first splitting logical module for splitting a first access command into at least two second access commands based on an access address of the first access command; and at least two storage array modules, each of which is configured to perform a corresponding access operation based on one of the at least two second access commands of the first splitting logical module. According to the embodiments, the first access command with relatively long burst is split into second access commands with smaller granularity, and the at least two storage array modules are parallel accessed, whereby the at least two storage array modules can respond in parallel, effectively reducing response time of the first access command and access time of each master when parallel access of masters exists, then improving access efficiency.

Storage method capable of being concurrently accessed by splitting access command, electronic device and computer readable storage medium implementing the same

The present invention relates to a supported hybrid vanadium-chromium-based catalyst, characterized in the catalyst is supported on a porous inorganic carrier and a V active site and a inorganic Cr active site are present on the porous inorganic carrier at the same time. The present invention further relates to a process for producing a supported hybrid vanadium-chromium-based catalyst. The invention also provides the preparation method of the catalyst, titanium or fluorine compounds, vanadium salt and chromium salt according to the proportion, different methods of sequence and load on the inorganic carrier, after high temperature roasting, still can further add organic metal catalyst promoter prereduction activation treatment on it. The catalyst of the present invention can be used for producing ethylene homopolymers and ethylene/&#x3b1;-olefin copolymers. The hybrid vanadium-chromium-based catalyst can have high activity and produce polyethylene polymers having the properties of broad molecular weight distribution (Part of the products are bimodal distribution) and excellent &#x3b1;-olefin copolymerization characteristic.
