Abstract:
A memory can be a sum addressed memory (SAM) that receives, for each read access, two address values (e.g. a base address and an offset) having a sum that indicates the entry of the memory to be read (the read entry). A decoder adds the two address value to identify the read entry. Concurrently, a predecode module predecodes the two address values to identify a set of entries (e.g. two different entries) at the memory, whereby the set includes the entry to be read. The predecode module generates a precharge disable signal to terminate precharging at the set of entries which includes the entry to be read. Because the precharge disable signal is based on predecoded address information, it can be generated without waiting for a full decode of the read address entry.
