Abstract: This application provide a retransmission control method, a communications interface, and an electronic device. When a transmit end transmits a first data packet to a receive end and does not receive an acknowledgement corresponding to the first data packet within a first RTO, the transmit end retransmits a second data packet based on a second RTO. The second data packet is a data packet transmitted by the transmit end after the transmit end transmits the first data packet. The second RTO is related to a receive timestamp of the acknowledgement corresponding to the first data packet and a transmit timestamp of the first data packet.

Abstract: A method comprises receiving a request to access a memory array having one or more memory erase units with a data area of flash array and with a specific amount of memory which offers small data programming capability, the specific amount of memory configured to be erased simultaneously or sequentially with a main memory block of the memory array; and if the memory access request includes programming small data, then providing access to the specific amount of memory, or if the memory access request does not include programming small data, then providing access to the data area of flash array. The size of the specific amount of memory may be pre-defined, and the specific amount of memory may be a different memory technology.
