Disclosed are a memory operating method, memory and electronic device. The memory follows a read-write parallel protocol and includes a plurality of memory banks, and the method comprises: writing data to a specified location of the first memory bank corresponding to a current logical address, and pre-reading original data in a specified location of the second memory bank corresponding to a next logical address in a current clock cycle; encoding the pre-read original data and data to be written next, when an instruction to encode based on the pre-read original data in a next clock cycle is obtained; and writing the encoded data to the specified location of the second memory bank in the next clock cycle. By pre-reading the original data corresponding to the incremental address in the current clock cycle, the present disclosure can accelerate an encoding operation that may occur next.

Memory operation method for unaligned write, memory and electronic device

Disclosed are a memory operating method, memory and electronic device. The memory complies with a read-write parallel protocol and includes a plurality of memory banks, and the method includes: sequentially mapping read and write transactions for consecutive logical addresses to different banks according to a predetermined transmission bit width by an address decoder, and arbitrating the read transaction and write transaction mapped to the same bank in a current clock cycle by an arbitration circuit, wherein in case that a specific low address bits of the logical address are the same, the read and/or the write transaction are mapped to the same bank. The disclosure avoids long-term occupation of a certain physical bank with specific low address decoding solution, thereby improving the execution efficiency of the read-write parallel protocol. Furthermore, an arbitration mechanism is introduced to arbitrate read and write conflicts for the same memory bank in each clock cycle.
