Memory system |
摘要 |
A memory system includes: a memory controller which executes a data access process with an external device using an access unit; a first memory which is connected to the memory controller via a bus and has a first latency; and a second memory which is connected to the memory controller via a bus and has a second latency longer than the first latency. The access unit comprises a first access size assigned to the first memory and a second access size assigned to the second memory. The memory controller executes a data access process with the first memory using the first access size, and executes a data access process with the second memory using the second access size. |

1. A memory system comprising:
a memory controller which executes a data access process with an external device using an access unit; a first memory which is connected to the memory controller via a first bus and which has a first latency; and a second memory which is connected to the memory controller via a second bus and which has a second latency longer than the first latency; wherein the access unit comprises a first access size assigned to the first memory and a second access size assigned to the second memory, and the memory controller executes a first data access process with the first memory using the first access size, and executes a second data access process with the second memory using the second access size. |
