Abstract
A method of generating access signals for a memory array. The method includes receiving a synchronization signal and generating a wordline select signal in response to the synchronization signal. A local precharge signal is generated in response to the synchronization signal. A precharge signal is generated in response to the synchronization signal, the precharge signal being a row signal for regulating memory array read operations. A write signal is generated in response to the synchronization signal, the write signal being a row signal for regulating memory array write operations.
Claims19
A method of generating access signals for a memory array, the method comprising:
- receiving a synchronization signal;
- generating a wordline select signal in response to the synchronization signal;
- generating a local precharge signal in response to the synchronization signal;
- generating a precharge signal in response to the synchronization signal, the precharge signal being a row signal for regulating memory array read operations;
- and
- generating a write signal in response to the synchronization signal, the write signal being a row signal for regulating memory array write operations.
A system for generating access signals for a memory array, the system comprising:
- a wordline driver generating a wordline select signal in response to a synchronization signal;
- a buffer generating a local precharge signal in response to the synchronization signal;
- precharge logic generating a precharge signal in response to the synchronization signal, the precharge signal being a row signal for regulating memory array read operations;
- and
- a write driver generating a write signal in response to the synchronization signal, the write signal being a row signal for regulating memory array write operations.
