Abstract

The embodiment of the invention discloses a transaction submission method, which comprises the steps of receiving submission requests of M pieces of data blocks for submitting transaction association to an external memory. Wherein, the external memory is divided into N groups and each group comprises 1 idle memory cell; M and N are integers; 0<=M<=N. if the quantity of the data blocks to be written in each group of the external memory is less than 2, the source data in each data block in the M pieces of data blocks is obtained; the group where the data block written in is determined, and each data block and associated source data are written in an idle memory cell of a corresponding group respectively. A transaction submission apparatus is provided. According to the invention, data writing frequency can be reduced and transaction submission throughput can be provided.

Description

technical field [0001] The invention relates to the computer field, in particular to a method and device for transaction submission. Background technique [0002] The traditional DRAM (Dynamic Random Access Memory, DRAM for short) based memory has increasingly become an important obstacle restricting the improvement of system computing performance due to its limitation in capacity expansion. A resistive memory device (Resistive Memory) is gradually showing the trend of replacing the existing memory. Resistive memory devices store information that stores "0" and "1" respectively through different impedance states of the medium. More representative resistive memory devices include - Phase Change Memory (PCM, Phase Change Memory), Magnetic Random Access Memory (MRAM, Magnetic Random Access Memory), Spin Transfer Torque Random Access Memory (STT-RAM, SpinTorque Transfer Random Access Memory), etc. However, the write performance of most resistive memory devices is far from tha...
