Abstract
In a memory device, data can be transmitted from a first CPU to a second CPU via an individual register or a shared SRAM, for example. The data transmitted from the first CPU to the second CPU via the individual register also passes through a FIFO. When first data is transmitted via the shared SRAM and then second data is transmitted via the individual register, for example, and if the first data transmission is adjusted by a SRAM controller and put into a waiting state at the FIFO, the second data transmitted via the individual register also passes through the FIFO, preventing the second data transmission from being completed earlier than the first data transmission. The data transmissions can therefore be completed appropriately. This in turn increases reliability of the memory device.
