TapeOutWorld 科普 NAND 与 LATCH 两个基础元件TapeOutWorld explains NAND and LATCH, TapeOut's two base elements
TapeOutWorld 发文科普 TapeOut 的两个基础元件：NAND 接受两个输入，输出二者交集取反，理论上任何逻辑运算都可以由 NAND 搭建；LATCH 保存 1 bit 状态，并在每个 tick 更新。文中指出，只有 NAND 的世界没有记忆，而没有记忆就不能称之为计算机。TapeOutWorld published an explainer on TapeOut's two base elements: NAND takes two inputs and outputs the negation of their intersection, and in theory any logic operation can be built from NAND; LATCH holds one bit of state and updates on every tick. The post notes that a world of only NAND has no memory, and without memory it cannot be called a computer.
