Problems solved by technology

[0008] 2. Double RANK will add a small number of address group signals, in which the number of clock and control signals is doubled and the topology of 1 push 9 Fly-by is maintained. The number of address and command signals remains unchanged but the load is increased to 1 push 18 Fly-by topology. Aggravation has an impact on the quality of signal transmission and affects the efficiency of memory access
[0009] 3. The number of signals in the address group of the dual RANK remains unchanged, but the topology changes from point-to-point to 1 push 2. The increased load will affect the quality of signal transmission and the increase of signal rate (may lead to a decrease in bandwidth)
[0016] However, high-speed memory chips are an inevitable choice for high-performance computing, so the above method only has a limited effect on increasing the assembly density, and cannot effectively increase the memory access bandwidth while increasing the assembly density.

Abstract

The invention discloses a storage body structure. Nine front-surface storage body units, namely a front-surface first storage body unit, a front-surface second storage body unit, a front-surface third storage body unit, a front-surface fourth storage body unit, a front-surface fifth storage body unit, a front-surface sixth storage body unit, a front-surface seventh storage body unit, a front-surface eighth storage body unit and a front-surface ninth storage body unit, are arranged on the front surface of a printed plate side by side. Nine back-surface storage body units, namely a back-surface first storage body unit, a back-surface second storage body unit, a back-surface third storage body unit, a back-surface fourth storage body unit, a back-surface fifth storage body unit, a back-surface sixth storage body unit, a back-surface seventh storage body unit, a back-surface eighth storage body unit and a back-surface ninth storage body unit, are arranged at the positions, opposite to the front-surface storage body units, of the back surface of the printed plated side by side. The nine front-surface storage body units arranged on the front surface of the printed circuit belong to a first path of storage control; and the nine back-surface storage body units arranged on the back surface of the printed circuit belong to a second path of storage control.

Description

technical field [0001] The present invention relates to computer technology, and more specifically, the present invention relates to a storage body structure and a storage body arrangement method. Background technique [0002] To date, memory banks built from various generations of memory chips have been an indispensable basic element in the field of high-performance computing. With the rapid development of high-performance processors, the relative lag of memory development has introduced the problem of "storage wall", which mainly includes storage depth (depending on storage bit width and single-bit storage density), storage bandwidth (depending on storage At the same time, high-performance computing itself has increasingly stringent requirements for memory assembly density. As an important fixed component of computing node layout, increasing the main memory layout density is conducive to improving the assembly density. . [0003] At present, the commercial memory standar...
