Title: Refresh controlling system
Inventor: OONO KUNIO
IPC: G11C11/406
Filed: 1981-06-10
Abstract: PURPOSE:To obtain a refresh controlling system enabling the using efficiency of storage devices to be improved by detecting unrefreshed memory banks and refreshing only those banks by the storage devices themselves. CONSTITUTION:If unrefreshed memory banks exist in memory banks 22-25 after passing a prescribed period from the transfer of a refresh request to a CPU, the unrefreshed banks are detected by corresponding refresh completion bank registers 8-11 and an incompletion signal 118 outputted from a NAND gate 17 is turned to ''1''. A control circuit 6 transfers an internal refreshing signal 112 which is ''1'' at the incompletion of refreshing to the CPU. By an internal refresh starting signal 113 outputted from an AND gate 115 by these signals 128 and 112, a bank priority deciding circuit 13 to which the contents stored in the registers 8-11 are applied is started. Thus, the unrefreshed banks 22-25 are refreshed by the corresponding storage devices, improving the using efficiency of the storage devices.
