摘要： Disclosed is a semiconductor storage device in which control is performed in such a manner that if the refresh operation is not being performed when a chip-select signal undergoes a transition from an inactive (standby) state to an active state, read or write access is executed immediately and if the refresh operation is in progress when the chip-select signal undergoes a transition from the inactive state to the active state, a wait signal for causing read or write access to wait is generated by a wait generating circuit.

摘要： According to one embodiment, an asynchronous static random access memory (SRAM) circuit (100) can provide reduced power consumption and high-speed access. An SRAM circuit (100) may include address registers (122 and 128) that can store a write address from one write operation and output the stored write address during a subsequent write operation. A data register (138) may also be included that can store write data from one write operation and output the stored write data during a subsequent write operation. Memory cells of a memory cell array (102) may be selected according to a pulse word signal PW. A pulse word signal PW can be generated in response to transitions in an address and transitions in a write enable signal /WE. Hit address comparators (220) within address registers (122 and 128) in combination with a hit AND gate (136) can activate a HIT ALL signal when a stored write address matches an applied read address. When the HIT ALL signal is activated, an output circuit (118) can output stored write data instead of an output from a sense amplifier circuit (116).

摘要： According to the disclosed embodiments, a semiconductor memory device may include an address register circuit (406) and data register circuit (411) that can store a write address and write data from one write operation and output the stored write address and write data during a subsequent write operation. In a dynamic random access memory (DRAM) embodiment (400), a precharge and/or refresh operation may follow the writing of previously stored write data. Such an arrangement may reduce and/or eliminate a read after write timing requirement (TWR), which can improve the operating speed of the semiconductor memory device.
