Problems solved by technology

[0005] Also, in DRAM, some data buses may be shared
When reading data continuously, if the CRC operation timing is not controlled, data conflicts are likely to occur
Especially when the CRC calculation takes a long time, if the CRC calculation has not been completed but the next data has been sent, errors are prone to occur

Embodiment Construction

[0028] Please refer to figure 1 , which shows a schematic diagram of memory access control according to an embodiment of the present invention. A memory bank (memory bank) 101 is coupled to a register 102 and a first-in-first-out register (FIFO) 103 through a data bus (ie, a bus, hereinafter referred to as a bus) 110 . The CRC operation unit 105 is coupled to the register 102 and the I / O buffer 106 . An off-chip driver calibration circuit (off-chip driver, OCD) 104 is coupled to the first-in-first-out register 103 . The decoder 107 is coupled to a read timing simulator (read timer) 108 . A CRC timing simulator (CRC timer) 109 is coupled to the read timing simulator 108 and the I / O buffer 106 . The decoder 111 is coupled to a column decoder 112 .

[0029] The data read from the memory bank 101 is sent to the register 102 and the first-in-first-out register 103 through the data bus 110 .

[0030] The register 102 is used for temporarily storing the read data, so that the s...

Abstract

The invention relates to a memory reading-operation control method which respectively decodes received reading instructions and address signals into internal address reading signals and internal address signals so as to read data from the data storage part of the memory. Then, the read date is simulated into the time or a transmission path required by a ready state. When the simulated result indicates that the data is ready, the read data is inspected for mistakes, and the time spent on mistake inspection is simulated and when the simulated result indicates that the mistake inspection is completed, and the mistake inspection result is sent out to the external part of the memory.

Description

technical field [0001] The present invention relates to a kind of read operation control method of memory (memory, that is storage medium, memory, internal memory, hereinafter all referred to as memory), especially relate to a kind of reading of memory that can increase the correct rate of data reading Operational control method. Background technique [0002] Dynamic Random Access Memory (DRAM) has the characteristics of low cost and large capacity, so many electronic system products use it as a memory solution, and it is one of the indispensable components of electronic system products one. In terms of applications, DRAM is still mainly used in information products, such as desktop computers, notebook computers, DRAM upgrade modules, servers and workstations. [0003] In a communication system or a computer system, a cyclic redundancy check (CRC) can be used to improve the error checking capability of the DRAM. After data transmission or data storage, CRC can be used to ...
