Configurable multi-port memory device and method thereof

摘要

Embodiments of a multi-port memory device may include a plurality of ports and a plurality of memory banks some of which are native to each port and some of which are non-native to each port. The memory device may include a configuration register that stores configuration data indicative of the mapping of the memory banks to the ports. In response to the configuration data, for example, a steering logic may couple each of the ports either to one or all of the native memory banks or to one or all of the non-native memory banks.

主权项

1. A bank/port circuit, comprising:
a configuration register configured to store configuration data indicative of the manner in which each of a plurality of bank are to be mapped to a port; steering logic coupled to the configuration register, the port, and each of the banks, the steering logic configured to be responsive to any configuration data received from the configuration register to selectively couple the banks to the port; a native bank coupled to the steering logic and configured to store data and perform memory commands; a command decoder coupled to the steering logic through a native command bus, wherein the command decoder is configured to decode commands for the native bank; and an address decoder coupled to the steering logic through a native address bus, wherein the address decoder is configured to decode commands for the native bank.
