Memory control device |
摘要 |
A memory control device that can reduce a power consumption at the time of writing a memory. The memory control device includes a data output buffer circuit that burst-transfers data to a memory device through a data bus, and a mask signal output buffer circuit that outputs, to the memory device, a mask signal indicative of data that prohibits write into a memory cell within the memory device among the data. The data output buffer circuit puts an output node into a high impedance state when the mask signal is indicative of write prohibition. |

1. A memory control device, comprising:
a data output buffer circuit that burst-transfers data to a memory device through a data bus; and a mask signal output buffer circuit that outputs, to the memory device, a mask signal indicative of data that prohibits write into a memory cell within the memory device among the data, wherein the data output buffer circuit puts an output node into a high impedance state when the mask signal is indicative of write prohibition. |
