9 / 19 page 1Mx36 & 2Mx18 Flow-Through NtRAMTM - 9 - K7M321835C K7M323635C Rev. 1.1 June 2007 SYNCHRONOUS TRUTH TABLE Notes : 1. X means "Don ′t Care". 2. The rising edge of clock is symbolized by ( ↑). 3. A continue deselect cycle can only be enterd if a deselect cycle is executed first. 4. WRITE = L means Write operation in WRITE TRUTH TABLE. WRITE = H means Read operation in WRITE TRUTH TABLE. 5. Operation finally depends on status of asynchronous input pins(ZZ and OE).
