PURPOSE:To increase a memory capacity without extending an address, and also to easily handle a data having length of >=(two words), by assigning a data of >=(two words) to one address of a memory. CONSTITUTION:When (n) address is designated to an address signal 11 and a write signal 13 is outputted, a data signal 14 is sent to a memory 4.1 through an input control part 6, and is written in n-th memory by a memory driving circuit 3. In a state that the (n) address has been latched by a register 2, when a+1 address is designated to the signal 11 and the signal 13 is outputted, the signal 14 is written in the (n) address of the memory 4.1+1. Accordingly, when a+1 address is made (a) address, a+1 address...a+m-1 address, a data can be written in 1st, 2nd... m-th depth of (n) address. |
